Matthew 28:16-20 (KJV)
16 Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them.
17 And when they saw him, they worshipped him: but some doubted.
18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

The Fruit of the Spirit is Joy

Galatians 5:22-23 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, 23 Meekness, temperance: against such there is no law.

Biblical joy is a cheerfulness, a calm delight and gladness in the heart of God’s children as the Holy Spirit’s fruit. It is the joy that comes with living a victorious Christian life according to God’s will. Jesus taught that obedience to God’s Word brings biblical joy in John 15:10-11 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father’s commandments, and abide in his love. 11 These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.
