Revelation 3.20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
This is one of the classically misused verses for evangelism. The church has decided that the verse portrays Jesus Christ patiently waiting for the sinner to come to his senses and open the door. This is not the case. This verse needs to be understood in the light of Luke 12.36-40 which speaks of the Great Marriage Feast. Jesus Christ will come to this feast with triumph and power and we will sup with Him in victory! Richard Bauckham says, “Jesus’ knock is not that of a homeless traveler, standing outside the locked door of a human heart, seeking shelter. Rather, he is the master of the house, and he will burst through the door in sovereign judgment!”
It reminds me of a conference that Francis Nigel Lee did at Southfield a number of years ago when he said (speaking of Psalm 110), "This is no namby pamby Arminian Jesus knocking on the door of your heart saying, hey buddy its cold outside, could you let me in and spare me dime?"
We serve an all power Savior who will save whom he desires, yet is gracious enough to invite even the most back-slidden of churches to hear his call to repentance and invite them to the marriage feast!
