The burden imparted by God is lifted once we have prayed, but the heaviness from the enemy cannot be raised unless we fight and resist in prayer.
Watchman NeeThe author tells a story wherein a missionary friend of his was invited by unbelievers on a train ride to play cards. The friend declined, saying that he did not bring his hands with him. He explained to the astonished group that the hands attached to what they saw as his body belonged to the Lord, and he was thereby able to explain the Gospel.
