Experience God’s Mercy Daily
Commenting on Psalm 32:1-2, John Calvin writes,

The more eminently that any one excels in holiness, the farther he feels himself from perfect righteousness, and the more clearly he perceives that he can trust in nothing but the mercy of God alone. Hence it appears, that those are glossly mistaken who conceive that the pardon of sin is necessary only to the beginning of righteousness. As believers are every day involved in many faults, it will profit them nothing that they have once entered the way of righteousness, unless the same grace which brought them into it accompany them to the last step of their life.
Or, as Paul put it in Colossians 2:6,
As you have received Christ Jesus the Lord, so walk in him.
-John Calvin, Commentary on the Book of Psalms (Baker reprint 2003), 526.
