…for He shall save His people from their sins. – Matthew 1:21

It is Christ that died… – Romans 8:34

Now, there is but one Judge-the man Christ Jesus. It is He that died for us. He cannot bring us in debt to divine justice; for in His own hands and feet are the nail-prints, which are the receipts of justice in full settlement of all claims against us. He has paid all we owed and He will vindicate His own death, and claim for the travail of His soul its due reward, which is the forgiveness and the salvation of all guilty men who have come and put their trust in Him. Wherefore, since it is only our Judge who can condemn us, and since He is the very Person who has paid our debt for us, and put our sin away, we dare to repeat again, with additional emphasis, our ringing challenge to all the universe, “Who is he that condemneth?” We stand boldly in front of all our foes, because we know that we are free from the evil which once condemned us: it is all gone. Our confidence is therefore strong, and it is so because Christ’s dying has removed all sin from all believers.

“Look,” says one, “there is sin. It is true that you are a believer, but you have sinned often, for years, in all sorts of ways.” Yes, as we look, we must confess that it is true, there is the sin. But yonder is the Saviour, and He is called Jesus, “For He shall save His people from their sins.” He has come on purpose to put away our sin, and when He died, He made an end of it. The answer, therefore, to the statement, “There is sin,” is this, “Christ has died.”

There is great sin; that we know only too well: but we also rejoice in the knowledge that there is a great atonement to cover all our sin, “For it is Christ that died.” ~ C.H. Spurgeon
