The Instruments of Good Works

Do not render evil for evil (1 Thess 5:15; 1 Pet. 3:9). Do no wrong to anyone; rather, bear patiently the wrong done to yourself. Love your enemies (Matt. 5:44; Luke 6:27). Do not render cursing for cursing, but rather blessing. Bear persecution for justice's sake (Matt 5:10).
