Galatians 4:12

This is addressed to his Jewish disciples, and he brings his own example forward, to induce them thereby to abandon their old customs. Though you had none other for a pattern, he says, to look at me only would have sufficed for such a change, and for your taking courage. Therefore gaze on me; I too was once in your state of mind, especially so; I had a burning zeal for the Law; yet afterwards I feared not to abandon the Law, to withdraw from that rule of life. And this ye know full well how obstinately I clung hold of Judaism, and how with yet greater force I let it go. He does well to place this last in order: for most men, though they are given a thousand reasons, and those just ones, are more readily influenced by that which is like their own case, and more firmly hold to that which they see done by others. Observe how he again addresses them by a title of honor, which was a reminder moreover of the doctrine of grace. Having chid them seriously, and brought things together from all quarters, and shown their violations of the Law, and hit them on many sides, he gives in and conciliates them speaking more tenderly. For as to do nothing but conciliate causes negligence, so to be constantly talked at with sharpness sours a man; so that it is proper to observe due proportion everywhere. See then how he excuses to them what he has said, and shows that it proceeded not simply because he did not like them, but from anxiety. After giving them a deep cut, he pours in this encouragement like oil; and, showing that his words were not words of hate or enmity, he reminds them of the love which they had evinced toward him, mixing his self-vindication with praises. Therefore he says, "ye did me no wrong."
