The classic: all your heart, not your own understanding.
Trust in the Lord with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight. Proverbs 3:5-6
Commit your way to the Lord. Trust also in him, and he will do this. Psalm 37:5
Lord, I want to trust You with all my heart, not only with the parts that are easy. I don’t understand everything, and I’m done pretending I do. Make my paths straight. Show me the next step, and I’ll take it. In Jesus’ name, amen.
