Whatever you do, work at it with all your heart as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ that you are serving. Colossians 3:23-24

Therefore, my dear brothers and sisters, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain. 1 Corinthians 15:58

Whatever your hand finds to do, do it with all your might, for in the realm of the dead where you are going, there is neither working or planning nor knowledge or wisdom. Ecclesiastes 9:10

Commit the Lord whatever you do, and he will establish your plans. Proverbs 16:3

All hard work brings a profit, but mere talk leads only to poverty. Proverbs 14:23

Serve wholeheartedly, as if you were serving the Lord, not people, because you know that the Lord will reward each one for whatever good they do. Ephesians 6:7-8
