“It is He [Jesus] who bore the sins of the world. This is the one satisfaction; this is the one washing, by which we are saved. And the basis of salvation is that when you hear this, you should not be unbelieving toward divine revelation but believe it. The fact that a new life should follow does not belong to satisfaction, but to the obedience you owe. Because the Holy Spirit arouses this in us, we cannot claim any merit of ours from it to reconcile God and to expiate sins which, we are taught, have already been expiated through Jesus Christ.
Only that satisfaction is true which is called and is satisfaction of faith, namely, that Christ Jesus bore your sins.
If this satisfaction stands alone and pure without your flesh, then you may zealously exercise charity, serve your calling, and do everything that the Word of God permits you to undertake. This obedience is pleasing and acceptable to God because it is done with the right aim, namely, of obeying God and not setting up your own satisfaction.
