"Let us recognize, then, the difference between the Head and the members. Let us learn that though by nature we are entirely given to evil, and although God may have regenerated us in part, still our flesh does not cease to chafe against God. However, by virtue of the obedience which we see in our Lord Jesus Christ, we do not cease to be acceptable to our God. If we do not yet do the good that we will, but the evil oftentimes pushes us, and there may be many failures, or perhaps we may be too slow to do good, let us look at what the Son of God suffered in order to make reparation for all our faults. Let us notice how He fought in such a way that there was no contradiction in Him when our crimes and sins were imputed to Him, as was explained more at length this morning. Let us see, then, how our Lord Jesus has made satisfaction in everything and for everything, but we today, although having taken the trouble to obey God, are not able to succeed, but we always droop our wings, must constantly repeat this: that we know that we shall not cease to be acceptable to God and that our imperfections will always be abolished by the obedience of our Lord Jesus Christ, so that they will not come into account before God. Besides, may each one according to the measure of his faith and of the grace which he has received exert himself to fight until we come to the heavenly rest. Seeing our weaknesses are still so great, being convinced that we shall not even know how to have a single good thought, and that having stumbled we shall not be able to raise ourselves, unless God extended to us His hand and strengthened us each minute, may we be advised to pray that He may augment in us the graces of His Holy Spirit; as He has promised it to us, and offers to us Jesus Christ for our Head and Captain, in order that after we are able to arrive at the victory which He acquired for us, of which we already experience the fruit, we shall experience it in perfection."
Now we shall bow in humble reverence before the majesty of our God.John Calvin, Second Sermon on the Passion of Our Lord Jesus Christ - Matthew 26:40-50
