Do you want to walk in the blessings of the Lord? Repentance must proceed blessings.

“So rend your heart, and not your garments; Return to the Lord your God,
For He is gracious and merciful, Slow to anger, and of great kindness; And He relents from doing harm. Who knows if He will turn and relent, And leave a blessing behind Him—A grain offering and a drink offering For the Lord your God?” Joel 2:13-14

If you don’t know what to say to the Lord, David’s prayer to the Lord could be a good start.

“Have mercy upon me, O God, According to Your lovingkindness; According to the multitude of Your tender mercies, Blot out my transgressions.” Psalm 51:1
