it's an amazing start, i highly recommend reading the early church fathers and the lives of the saints!

Revelation 3:20

"Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me."

Matthew 7:7-8

"Ask, and it will be given to you; seek, and you will find; knock, and the door will be opened to you."
