I will make known the LORD’s loving devotion and His praiseworthy acts, because of all that the LORD has done for us—the many good things for the house of Israel according to His great compassion and loving devotion. — Isaiah 63:7

The prophet resolves to recount the lovingkindnesses of the Lord, according to all He has bestowed on us. That's a healthy spiritual discipline — preaching the goodness of God to your own soul. He drew you up out of a horrible pit and set your feet on a rock. God demonstrates His own love toward us, in that while we were still sinners, Christ died for us. He's sealed you with the Holy Spirit of promise, the guarantee of your inheritance.
