An ethic of hope pervades the New Testament:-

1. It is an ethic of pilgrimage: one should see oneself in this world as a stranger traveling home (1 Pet. 2:11; Heb. 11:13).
2. It is an ethic of purity: everyone who really hopes to be like Jesus when he appears “purifies himself, just as he is pure” (1 John 3:3).
3. It is an ethic of preparedness: we should be ready to leave this world for a closer relationship with Christ our Lord at any time when the summons comes (2 Cor. 5:6–8; Phil. 1:21–24; cf. Luke 12:15–21).
4. It is an ethic of patience: “if we hope for what we do not yet have, we wait for it patiently” (Rom. 8:25; cf. 5:1–5, where the Greek word for “patience” is translated “perseverance” to bring out its nuance of stubborn persistence in face of pressures).
5. And it is an ethic of power: the hope gives strength and confidence, energizing effort for running the race, fighting the good fight, and enduring the “light and momentary troubles” (2 Cor. 4:17) that still remain before we go home (Rom. 8:18; 15:13; 2 Tim. 4:7–8).
