God Knows and Sees

The secret [of the sweet, satisfying companionship] of the Lord have they who fear (revere and worship) Him, and He will show them His convenant and reveal it [deep, inner] meaning.
Psalm 25:14

Nobody else may see the things you do, but God sees them all. Everytime you pray, God sees it. Everytime you do an act of kindness secretly, God sees it and plans a reward togive you openly (see Matthew 6:1-6)
Serve the Lord in all that you do today. The Word says "In the morning sow your seed, and in the evening withhold not your hands, for you know not which shall prosper, whether this or that, or whether both alike will be good" (Ecclesiates 11:6). God will prosper what you do for Him.
