Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me.
Revelation 3:20 NKJV
What a loving, patient and humble God is Jesus. This is an amazing analogy to salvation and joining in the ultimate relationship.
Its clearly open for anyone. He died for all as John 3:16 says, “For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.”
God is love and surely has given us choice and free will to respond to His calling. By faith, all things are possible.
