Moreover the law entered, that the offense might abound. But where sin abounded, grace did much more abound. Romans 5:20

Grace covers and cleanses every sin. The greater the sin, the greater the grace to cover it. There is no sin too bad or too many sins for God’s grace to handle. Where sin abounds, grace does much more abound. I don’t care how bad you’ve messed up, or how many times you’ve fallen, God’s grace is sufficient to cover and cleanse you from all sin.
