Deuteronomy 4:29; Matthew 7:7-8

29 But if from there you seek the LORD your God, you will find him if you seek him with all your heart and with all your soul.
7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8 For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.
