His afterlife was inspired by the one principle of self-sacrifice, the ministry of love. "I am debtor," he said, "both to the Greeks, and to the barbarians; both to the 66 wise, and to the unwise." "The love of Christ constraineth us." Romans 1:14; 2 Corinthians 5:14.

Hans senere liv var præget af et eneste grundprincip: selvhengivelse og udøvelse af kærlighed. Han sagde:»Både til grækere og barbarer, både til vise og uforstandige står jeg i gæld."»Thi Kristi kærlighed tvinger os.« Rom. 1,14; 2Kor. 5,14.
