According to the bible, the unsaved person is dead in trespasses and sins. The unsaved person cannot understand spiritual things because the unsaved person is not spiritual, (born again), but rather is carnal, (in the unregenerate sinful nature), SOLD UNDER SIN.
The bible also says that the unsaved person has the devil’s nature and in fact belongs to the devil or is the devil’s seed. “Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. And because I tell you the truth, ye believe me not.” John 8:44
The one who believes in Jesus Christ is adopted by God as his child when becoming “born again” Translated being,(To change from one form, function, or state to another, convert or transform) and are set free from the power of darkness and translated into the Kingdom of his dear Son.
To be saved from sin means to be translated, changed, born again, having a new heart. So when the bible says to believe with the heart and you will be saved, what that verse is saying is; one must believe with the spirit that is now born again. It does not mean to have an intellectual (physical mind/body) assent to the gospel. Scripture tells us that even the devils believe the gospel. They believe that Jesus died for the sins of his elect and that he rose from the dead. That kind of belief does not save!
Satan’s seed many times believe with the head the salvation message but are not really born of the Holy Spirit. Judas believed with the head. He walked with Jesus, saw all the miracles BUT he did not have divine revelation of Jesus in the same way that Peter did. Jesus was amazed that Peter knew who he was? Why? Because he knew that no one could really believe that Jesu was the Son of God unless the Father revealed who Jesus was.
Under the law, the Spirit would come upon a person and reveal himself. That is how God had relationship with the prophets. However, those were temporary incidences. This is the experience Peter had because until Jesus rose from the dead and sprinkled his blood on the mercy seat and sent the Holy Spirit to make people born again, God’s elect were circumcised in the flesh under the law. Under the New Testament to become one of Gods elect one must be circumcised by the Spirit in the heart. (spirit of man)
Another example of a person who believed with the head but not the heart is Simon the sorcerer. Simon believed but Peter told him that his heart (spirit) was not right before God. What was Peter saying? That Simon was not really saved. He was not born again. He “believed” with his intellect but he did not believe with the heart unto salvation.
“But there was a certain man, called Simon, which beforetime in the same city used sorcery, and bewitched the people of Samaria, giving out that himself was some great one: To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God. And to him they had regard, because that of long time he had bewitched them with sorceries. But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women. Then SIMON HIMSELF BELIEVED ALSO AND WHEN HE WAS BAPTIZED, he continued with Philip, and wondered, beholding the miracles and signs which were done. Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John: Who, when they were come down, prayed for them, that they might receive the Holy Ghost: (For as yet he was fallen upon none of them: only they were baptized in the name of the Lord Jesus.) Then laid they their hands on them, and they received the Holy Ghost. And when Simon saw that through laying on of the apostles’ hands the Holy Ghost was given, he offered them money, Saying, Give me also this power, that on whomsoever I lay hands, he may receive the Holy Ghost. But Peter said unto him, Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money. Thou hast neither part nor lot in this matter: FOR THEY HEART IS NOT RIGHT IN THE SIGHT OF GOD. Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee. For I perceive that thou art in the gall of bitterness, and in the bond of iniquity. Then answered Simon, and said, Pray ye to the LORD for me, that none of these things which ye have spoken come upon me.” (Acts, 8:9-24).
Now let’s take a look at those who believed with the heart in the New Testament. Both Cornelius and Lydia were seeking the Lord What did they each have in common? First of all they were seeking the Lord for his direction. Not their own purposes like Simon and the cults do, wanting to have God’s power for selfish motivation (usually power, money, and the praises of men, or to be justified by their own self righteousness) but because the Lord was revealing himself to them, drawing them by his Holy Spirit.
In the book of Romans Paul says that the unsaved do not seek after God. They do not want him and nor is he in their thoughts but those the Father is drawing are true seekers.
As it is written, There is none righteous, no, not one: There is none that understandeth, there is NONE THAT SEEKETH AFTER GOD. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. Romans 3:10, 11
“He is a rewarder of those who diligently seek Him” Heb 11:6
God was drawing Cornelius and Lydia to Himself. He sent someone to bring the Gospel to them and He opened their understanding so that they could believe the Gospel and be saved. In Romans chapter 10, Paul says that “Christ is the end of the law for righteousness to everyone that believeth”. No longer are God’s elect under the law because the new covenant of grace is now here which has been provided for by the death and resurrection of Jesus Christ. Under the new covenant one must be circumcised in the heart in order to put off the flesh rather than the physical act of circumcision under the law. When one is born again he is given a new nature, God’s nature is planted as a seed in him and grows daily to the perfect sature of Christ.
So we see that both Cornelius and Lydia were seeking the Lord and then the Lord send someone to preach the word of faith to them and then when they heard the word, they believed unto salvation and became born again into God’s kingdom. To believe with the heart means to receive the engrafted word into the spirit which was dead because of sin and to be born of God by being translated into a new creature. God must give the spirit life by his Spirit and then being risen from the dead the person can believe.
The preaching of the word is what produces that faith. Not preaching of man’s opinions but preaching scripture. However, remember that the word must be preached to opened hearts as Jesus said in his parable of the sower. The heart must be drawn and prepared by the Holy Spirit whose job is to convict of sin, righteousness, and judgment. Then when the word is sown into a prepared heart faith comes and that person believes unto salvation. Much prayer is needed in the heart preparation but I will save that for another sermon.
Romans 10:6-18 The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt BELEIVE IN THINE HEART that God hath raised him from the dead, thou shalt be saved. For WITH THE HEART MAN BELIEVETH unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report? So FAITH COMES BY HEARING,(the ability to hear) and hearing(the ability to hear) by the word of God. But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.
To believe with the heart Kardia in the Greek means to be born again in the spirit. When we are born again, the Holy Spirit comes to live in our spirits and then we are no longer in the flesh (carnal) but are spiritual, (in the spirit because we are joined to Gods Spirit) That is why Jesus said that “you must be born again to enter into Gods kingdom. “
And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. 1 Thessalonians 5:23
1 Peter 1:23, Being born again, not of corruptible seed,but of incorruptible, by the word of God, which liveth and abideth forever.
There are many who believe with the head the gospel message and the scriptures call these people false brethren or Apostates. They mimic real Christians, but when you examine their fruit closely you will see that they are fakes. The fruit is corrupt, they preach a different gospel trying to bring others into bondage of the law because they are under law, having not the spirit of God in their Spirit, Ephesisan 2 AND Colossians2 tells us that we must be made alive by the operation of God in order to be really saved and not an Apostate. Believe with the heart(spirit) unto salvation.
“And you hath he quickened, ( MADE ALIVE UNTO GOD) who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were BY NATURE THE CHILDREN OF WRATH, even as others. But God, who is rich in mercy, for his great love wherewith he loved us, Even when we were dead in sins, hath QUICKENED US TOGETHER IN CHRIST, (by grace ye are saved;) And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. For we are his workmanship,CREATED IN CHRIST JESUS UNTO GOOD WORKS, which God hath before ordained that we should walk in them.
Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwelleth all the fulness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power: In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: Buried with him in baptism, wherein also ye are RISEN WITH HIM THROUGH THE FAITH OF THE OPERATION OF GOD, who hath raised him from the dead. And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
