Rely on His Mercy!
Our fallen human nature prohibits us from remaining free from sin, even when we strongly desire to do so. Our daily sins, our thoughts, our words, what we do, and what we fail to do, are numerous on a daily basis. Ask for God's grace, try to refrain from sin, but most importantly, acknowledge and rely upon God's mercy always! If blessed with the opportunity to do so, the most important words we can ever utter on our death beds are simply the words, "Jesus, mercy". Saint Padre Pio, as he was approaching the time in which he would draw his last breath, continually prayed the words, "Jesus, Mary".
