Yes, God sees everything we do, both good and bad. We can't hide from him. God is happy when we do what is right and sad when we do wrong. God can reward us for doing what's right, even when no one else knows about it.
[Elihu is speaking] "For God watches the deeds of all mankind. He sees them all. No darkness is thick enough to hide evil men from his eyes." (Job 34:21-22)
Job 11:11; 31:4; Psalm 147:5; Matthew 10:28-31
