These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world. John 16:33 (KJV)
The Word of God produces wisdom when applied. Jesus Christ spoke on many subjects in John chapter sixteen for a very important reason. He touched on the work of the Holy Spirit, joy, and how to overcome the world. The words that proceeded out of His mouth gave the disciples peace of mind and heart.
