Verse 1-31 — Conversion is separating from the course and custom of this world, devoting ourselves to the conduct directed by the word of God. When we bind ourselves to do the commandments of God, it is to do all his commandments, and to look to him as the Lord, and our Lord.
Verse 32-39 — Having covenanted against the sins of which they had been guilty, they obliged themselves to observe the duties they had neglected. We must not only cease to do evil, but learn to do well. Let not any people expect the blessing of God, unless they keep up public worship. It is likely to go well with our houses, when care is taken that the work of God's house goes on well. When every one helps, and every one gives, though but little, toward a good work, the whole will come to be a large sum. We must do what we can in works of piety and charity; and whatever state we are placed in, cheerfully perform our duty to God, which will be the surest way to ease and liberty. As the ordinances of God are the appointed means of support to our souls, the believer will not grudge the expense; yet most people leave their souls to starve.
