In Genesis 7:16 God shut the door of the ark. God destroyed the world saving only Noah and his family from the flood.
In Matthew 25 five foolish virgins were unprepared to go into the wedding banquet and the door was shut, Matthew 25 vs 10.
In Revelation 3:20…”I stand at the door and knock, if anyone hears my voice and opens the door I will come in and eat with him and he with me.”
Jesus is knocking at the door of hearts. Will you respond and open the door? His grace will not last forever. He will one day close the door. Now the door swings both ways, but one day it will be forever closed. Only through Jesus, who is the door and also the way can the doors of Heaven swing open for you.
