88

In how many parts doth the true conversion of man consist?

In two parts: in the mortification of the old man (Rom. 6;6); and in the quickening of the new man (Col. 3;10).

89

What is the mortification of the old man?

It is a sincere sorrow of heart, that we have provoked God by our sins (2 Cor. 7;10); and more and more to hate and flee from them (Rom. 12;9).

90

What is the quickening of the new man?

It is a sincere joy of heart in God, through Christ (Ps. 51;8), and with love and delight to live according to the will of God in all good works (Rom. 7;22).

91

But what are good works?

Only those which proceed from a true faith (Heb. 11;6); are performed according to the law of God (Ezek. 20;19), and to his glory (1 Cor. 10;31), and not such as are founded on our imaginations, or the institutions of men (Deut. 12;8).
