“See that no one renders evil for evil to anyone, but always pursue what is good both for yourselves and for all.” 1 Thessalonians 5:15.
Perhaps the most comprehensive command Jesus CHRIST gave was the well-known “Love one another” (John 13:34). “As I have loved you, so you must love one another. By this everyone will know that you are MY disciples, if you love one another” (verses 34-35). This command is such a fundamental statement of our Christian duty that it is given again in John 15:12, 17; Romans 13:8; 1 Thessalonians 4:9; 1 Peter 1:22; 1 John 3:11, 23; 4:7, 11-12; and 2 John 5. This is the attitude in which we should always interact with one another… being responsibility that all members have toward one another.
Paul developed the command a little further: “Be devoted to one another in brotherly love. Honor one another above yourselves” (Romans 12:10). “Serve one another in love” (Galatians 5:13). He prayed that the LORD would help the Thessalonians’ love to increase not only for each other, but that their love would also increase for everyone else, even towards unbelievers until they come to the light (1 Thessalonians 3:12). In his second letter to the Thessalonians, he thanked GOD that their mutual love was indeed increasing (2 Thessalonians 1:3).
In Christ, we belong to each other and form one body (Romans 12:5). We are members of one another (Ephesians 4:25). “We have fellowship with one another” (1 John 1:7). Paul prayed that the Roman Christians would have “a spirit of unity among yourselves as you follow CHRIST Jesus” (Romans 15:5). To avoid division in the body, Paul wanted CHRIST-likes to “have equal concern for each other and offer hospitality to one another” as advised in 1 Corinthians 12:25; 1 Peter 4:9. Peace be unto You!
