Michelangelo, Sistine Chapel Wisdom from the Psalms, Daily Thoughts and Meditations, at One Place
"Sin is not merely doing what is wrong, but doing what is wrong in the sight of the Lord. God has offered us suggestions for living full and happy lives. Our being disobedient to those suggestions doesn't hurt God, it hurts us. God is saddened by our refusal to be obedient, but He is always willing to hear our petition for forgiveness, and He will show us His mercy. When we sin, it is a private matter between God and ourselves. Take your sins before God, repent of each one, and glory in the grace of God, by which we receive full pardon of all we do wrong."
Against You, You only, I have sinned And done what is evil in Your sight, So that You are justified when You speak And blameless when You judge.
Psalm 51:4
