God is ready to heal those who sincerely wish to amend their lives, but cannot take pity on the obstinate sinner. The Lord pardons sins, but He cannot pardon those who are determined to offend Him. He who receives pardon is pardoned through the pure mercy of God, and they who are chastised, are justly punished. God is not obliged to wait for your repentance..
– St. Alphonsus Liguori
