"'The long-suffering man abounds in understanding' (Prov. 14:29), because he endures everything to the end and, while awaiting that end, patiently bears his distress. The end, as St. Paul says, is everlasting life (cf. Rom. 6:22). 'And this is eternal life, that they might know You the only true God, and Jesus Christ whom You have sent' (Jn. 17:3)."

...we are not without hope of salvation, nor is it at all the right time for us to despair. All our life is a season of repentance, for God 'desires not the death of the sinner', as it is written, 'but that the wicked turn from his way and live' (cf. Ez. 33:11 LXX). For, if there were no hope of turning back, why would death not have followed immediately on disobedience, and why would we not be deprived of life as soon as we sin? For where there is hope of turning back, there is no room for despair.
