So, my dear brothers and sisters, be strong and immovable. Always work enthusiastically for the Lord, for you know that nothing you do for the Lord is ever useless. - 1 Corinthians 15:58
Father, though I can't always see results in my work for You, help me do it faithfully and tirelessly. I rejoice that nothing I do for Your kingdom will ever be done in vain. Strengthen me for the work ahead. Amen.
