“You may be now saved—completely saved, and live in the full enjoyment of that knowledge. ‘If thou seek him, he will be found of thee.’ The notion is that there are a great many very mysterious preliminaries, a great deal to do, and a great deal to be, and all quite beyond our power. It is not so, but seek him. We will tell you what that means, and he that seeks him finds him. ‘If thou seek him, he will be found of thee’” It has been supposed that we should want a good deal of help in seeking after salvation. Certain persons who step in to be absolutely necessary priests between us and God. A great delusion, but there be thousands who believe it and who fancy that God won’t hear them if they pray, except they have some respect for these human mediators. Away with the whole, away with any pretence for anyone to stand between the soul and God, save Jesus Christ. ‘If thou seek him, he will be found of thee.’” Charles Spurgeon
2 Chronicles 15:1 Now the Spirit of God came upon Azariah the son of Oded. 2 And he went out to meet Asa, and said to him: Hear me, Asa, and all Judah and Benjamin. The Lord is with you while you are with Him. If you seek Him, He will be found by you; but if you forsake Him, He will forsake you.
See James 4:8 for a confirmation of this promise.
