God restores broken people and uses their lives again. The speaker cites Psalm 103 to show God's mercy: He forgives completely, doesn't punish as deserved, and offers grace to those who fear Him.
And yes, God could use your life again because God restores broken people. I feel the anointing so strong right now. Even now as I'm talking to you, I feel just burdens being lifted from off of you. You realize that God has forgiven you. Psalm 103:8-14, the Lord is compassionate and merciful, Slow to get angry and filled with unfailing love, he will not constantly accuse us nor remain angry forever. He does not punish us for all of our sins. He does not deal harshly with us as we deserve, for his unfailing love toward those who fear him is as great as the height of the heavens above the earth.
