…Thou hast covered all their sin… Mercy and truth are met together; righteousness and peace have kissed each other. – Psalm 85:2, 10

“Thou hast covered all their sin.” I shall not have time to dwell upon the sweetness of this fact, but I invite you that believe to consider its preciousness; and I hope you who have not believed will feel your mouth watering after it; to know that every sin one has ever committed, known and unknown, is gone-covered by Christ. To be assured that when Jesus died He did not die for some of our sins, but for all the sins of His people; not for their sins up till now, but for all the sins they ever will commit!… The atonement was made before the sin was committed. The righteousness was presented even before we had lived. “Thou hast covered all their sin.” It seems to me as if the Lamb of God, slain from before the foundation of the world, had in the purpose of God, from the foundation of the world, covered all His people’s sins. Therefore, we are accepted in the Beloved, and dear to the Father’s heart. Oh! what a joy it is to get a hold of something like this truth, especially when the truth gets a hold of you-when you can feel by the inwrought power and witness of the Holy Ghost that your sins are covered-that you dare stand up before a rein-trying, heart-searching God, and give thanks that every transgression you ever committed is hid from the view of those piercing eyes through Jesus Christ your Lord. ~ C.H. Spurgeon
