Having joy is not synonymous with happiness or wealth or getting everything that we want. Joy sometimes comes at great cost and the blessing derived may bring contentment but may also bring suffering and persecution.
The definition of joy in the English dictionary is: a source of great happiness, success in doing, finding, or getting something. The Old English word for happiness was equated with having luck or being fortunate. Today it means feeling or showing pleasure or contentment, being fortunate and convenient.
The English word for Joy does not really define the right meaning in which the Hebrew and Greek words for joy are defined. For example, joy is some OT verses use the word simchah –mirth gladness ps.15:23 or Ranan-to overcome, to cry out for joy psalm 5:11 psalm 35: 27 or Samach- to rejoice, be glad psalm 21:1 psalm 51:8 or Rinnah-entreaty, supplication, proclamation, joy, praise, in proclamation, joy, praise ps. 30:5 ps.35:27 ps.126:5 or sasown- exultation, joy ps.35:27
The Greek word for joy is chara- meaning gladness, to be pleased; delighted, Mirth- (amusement, especially as expressed in laughter) grace, favor Matt. 28:8 Luke 1:14John 15:11John 16:24Romans 14:17 Gal.5:22
None of these words for Joy are defined in the Bible as being fortunate, convenient, happy, satisfaction enjoyment, or a state of happiness.
Biblical joy is equated with overcoming, praise, exaltation, or salutation (blessing), singing, shouting dancing, having grace and favor.
Then he said to them, “Go your way. Eat the fat and drink sweet wine and send portions to anyone who has nothing ready, for this day is holy to our Lord. And do not be grieved, for the joy of the LORD is your strength.” Nehemiah 8:10
In conclusion, Biblical joy is not the same as the English word for happy but rather is equated with praising and having God’s favor which brings victory which of course then brings absolute delight and laughter. Even in times of trouble we can have the joy of the Lord because we as Christians know that Jesus is the victor!
