'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).
