…for with the LORD there is mercy, and with Him is plenteous redemption. – Psalm 130:7

You seek pardon, look to the pardoning God. You will soon believe in forgiveness if you cause the first exercise of your faith to refer to the Forgiver, even Christ Jesus Himself. When you have believed in Him as able to say, “Thy sins be forgiven thee,” then you will believe in sins being forgiven. This is the natural order of things. To be healed, you believe first in the Healer. So, also, if you desire to believe for salvation, and to be assured that you have it, or may have it at once, the simple course-the natural course-is to believe in the Savior. When you have believed in the Savior, then you will believe in the salvation. If you know that Jesus can save you, if you desire to be saved, you will trust Him to save you. You will be readily able to believe that you can be saved when you trust in Jesus as able to save to the uttermost. Poor trembling heart, do not look at the blessing, and say, “Alas, it is too great!” Look at the Savior Himself! Is anything too great for Him to give who gave His heart’s blood to redeem? Do not say, “My heart is so hard, it cannot be changed.” Look at the Savior; is anything impossible to Him to whom the Father has committed all power? Is He not mighty to save? Fix your eye, first and foremost, upon Him who is both God and man, and has therefore power and sympathy, majesty and mercy, omnipotence and brotherliness. I pray you, do not consider so much the greatness of the effect as the unlimited power of the Cause. I may doubt my washing, but not when I believe in the cleansing virtue of the precious blood. It may be difficult to believe in my salvation, but not to believe in my Savior. It may be hard to hope for heaven; but the text sets me an easier task-“Let Israel hope in the Lord.“ ~ C.H. Spurgeon
