Luke 15:21

Now the good thoughts and resolutions of the sinner ripen into action, and the first of it is an expression of his convictions and humiliation by a humble confession of his sins, with their aggravations, as committed against God, and that in the sight of God, and this God his Father, his unworthiness so much as of the name of a son to such a Father. The petitionary part of what he resolved upon, Luke 15:19, is not here again repeated, but to be understood. Men may by the common grace of God, denied to no man, have some good thoughts, but they die away, and come to no maturity, unless the Holy Spirit of God breathes upon them, and maintains and upholdeth them in the soul; but where the Lord designs a thorough change in a soul, the Spirit of the Lord comes, and convinceth the soul of sin and of righteousness: and where he doth so, the resolution ripens into action, and produces in the soul a true and hearty contrition, and confession of its sin, with humble petitions and a resignation of itself to the Lord's will, and a casting of itself upon God's free grace and mercy.
