YEAH JESUS!! RAH! RAH! RAH!JG...I do not believe that a born again CHRIST FOLLOWING CHRISTIAN is lukewarm. But if you go down one street and invite someone to church, you will hear repeatedly of their wounded feelings and bitter experiences with church...and it is next to impossible to get them to come out.
They ARE NOT following Him. When He was hurt He did not quit. When He was tormented by whips and nails, He prayed for His tormentors. Psalm 78:9 says: "The children of Ephraim BEING ARMED turned back."
God has ARMED the Christian with faith and His Spirit. Those who turn back ARE LUKEWARM. In battle a turncoat or a sentry who goes to sleep is court martialed. Jesus said,'if you are lukewarm' He will spew you out.
He needs 'soldiers' fit for the battle. Lives depend on it. It is more important than an earthly battle.
