Hebrews 11:1-2 and Luke 11:9-10
Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony. So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened.
