The one who opens these doors is Christ. It is not feasible to open any of them without Christ. Until people confess their sins and accept Jesus as their Savior, others will never be able to pass through the door. He greets them warmly. He is calling them to come to Him for redemption with His arms extended in love. They get to make the decision. Because of His agony on the cross, He has made it possible. God bless us with these words in our hearts.
