Prayer for Endurance:
Father, I am thankful for the gift of life, and will remember that it is not my will, but Your will for my life. Lord, please sharpen my focus, order my steps, and strengthen me each day, to accomplish Your divine plan for my life. On days when I feel too spiritually fatigued to run the marathon of life, I know that baby steps count and will not succumb to condemnation. Seal in my heart and mind, Father, Colossians 1:11 “May you be strengthened with all power, according to his glorious might, for all endurance and patience with joy”.
