Blessed is the man to whom the Lord will not impute sin. – Romans 4:8

When you know that sin is forgiven, you cannot be sad as before. The thought of perfect pardon, if it does but fill the spirit, will thrust out gloom, and remove apathy. It will make the lame man leap as a hart: he may still be lame, but he will leap as if he were not. And the tongue of the dumb, even though untrained to speech, shall be made to sing concerning free grace and dying love. When the thoughts are concentrated upon the enjoyment of complete forgiveness, full reception into the divine favor, and the blotting out of sin, then is the heart lifted into the suburbs of heaven. My dear hearers, do you know what I am talking about? Some of you do, blessed be the name of the Lord; but I am afraid that some of you do not; and you never can know the sweetness of mercy until you first have tasted the bitterness of sin. You will never know how grace can heal until you have felt how sin can wound. There is no clothing you till you are stripped; there is no making you alive till you are killed; there is no filling you till you are empty. The Lord filleth the hungry with good things, but the rich He sends empty away. God Himself will never comfort you till you are driven to self-despair; and if you have already come to that, it is a great privilege to me to be allowed to tell you that the fact of forgiveness of sin is not only a doctrine of the creed, but it is a promise of God’s Word. “I believe in the forgiveness of sins:” this is no mere formula, but a realized fact with me. Removal of the penalty, removal of God’s offense against us, the clearing away of all the turbid waters within the heart, and the creation of joy and peace through perfect reconciliation to God-this is a summary account of the forgiveness of sin. It is a blessing vast and rich. ~ C.H. Spurgeon
