“Let Israel hope in the Lord; for with the LORD there is mercy, and with Him is plenteous redemption.” – Psalm 130:7
We do not read, “Let Israel hope for mercy;” but we read, “Let Israel hope in the Lord: for with the Lord there is mercy.” Neither does it say, “Let Israel hope for plenteous redemption;” but it is worded thus, “Let Israel hope in the Lord: for with the LORD there is…plenteous redemption.” To me this has the look of a very encouraging truth: the sinner is not to hasten with his first thoughts to the mercy that he wants, nor even to the promise of God to which he may look; but he is to go to the Lord Jesus’ Christ Himself, as the Lord of mercy, and fountain of redemption.
Look first to the Giver, and then to the gift. Look for the Helper, and then for the help. Do not be saying, “I long to be forgiven. I labor to believe that I am forgiven. I desire to be saved. I want to know that I am saved.” This is looking for the fruit, when you have need first to find the tree. Your first business, as a seeker of pardon and salvation, is to believe in Jesus Christ, that is, to trust yourself with the divine Savior. The natural order is, believe in the Promiser, and then you will believe the promise. You never say to yourself, “I should like to be able to take that man’s word. I will sit down and try to make my mind confident of the truth of what he says.” This would be a foolish and futile method of procedure. You follow a much more reasonable course: you enquire about the individual’s character and standing; you find out who he is, and what he is, and what he has done; and thus, you gather arguments for confidence and faith. You cannot help believing the promise when once you believe in the Promiser. Faith prizes the promises of her faithful God and calls them precious. ~ C.H. Spurgeon
