Matthew 7:7-8 (NIV)
7“Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.
8For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.
John 10:7-9 (ESV)
7 So Jesus again said to them, “Truly, truly, I say to you, I am the door of the sheep.
8 All who came before me are thieves and robbers, but the sheep did not listen to them.
9 I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture.
