Knock, Knock.....who's There?

Revelation 3:20 does NOT speak to evangelism. The Lord Jesus Christ does not stand at the door of an unsaved person's heart, hat in hand, knocking, knocking, knocking, calling, calling, calling, hoping, hoping, hoping, only to be disappointed in many cases! Why? Because He knows that the person inside is DEAD and can't, and won't, respond to Him (Ephesians 2:1). He is not knocking at the door of a house but of a tomb. He will remove the stone, so to speak, then He will speak life into the person by His word in the power of the Holy Spirit (see John 3 and John 11). Only when a person is born again, not by reason of blood, nor of the will of the flesh, nor of the will of man, but only of and by God can he be made alive and respond to Christ's call (John 1:13).
