That is a tough requirement.
I think I may have learned something in my old age. God is faithful. I am not. I was not faithful in my exercises to keep my stomach muscles strong due to a bad bad that caused pain. Strong stomach muscles reduces the pain. One day I told God He was faithful and I was not and skied Him for His faithfulness in consistent stomach exercies. Now I do it all most every day and nothing stops me—alll and exclusively to God alone—not me. Also, faithfulness is a fruit of the Spirit.
I enjoyed reading your comment. Blessings on your day.
