Jesus Himself spoke of the joy of the Lord in the teaching of talent’s where He gave one five talents, another two talents and another one talent. It was the one with five talents and the other with two talents that He said “Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy Lord”(Matthew 25:14-30).

There is great joy in the life of one who has been redeemed, even in the midst of tragedy there is comfort and renewed strength found in the Lord(Isaiah 51:9-13). ⁹ Awake, awake, put on strength, O arm of the Lord; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?¹⁰ Art thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over?¹¹ Therefore the redeemed of the Lord shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.¹² I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass;¹³ And forgettest the Lord thy maker, that hath stretched forth the heavens, and laid the foundations of the earth; and hast feared continually every day because of the fury of the oppressor, as if he were ready to destroy? and where is the fury of the oppressor?

It was Nehemiah, Ezra and the Levites that taught the people the law, and when the people wept because of the words they had heard they were told the joy of the Lord is your strength (Nehemiah 8:8-12).
