“See that no one pays back evil for evil, but always try to do good to each other and to all people.”
1 Thessalonians 5:15 NLT
Paul is explaining to new believers how they are supposed to treat one another. Believers are not supposed to seek revenge when wronged. Instead, we are to always strive to do what is good for one another, and for everybody else too.
A desire for revenge is incompatible with the believers life for several reasons: Wanting and getting revenge wastes time and energy. We could be spending our time and energy helping others and serving God. Folks, if someone wrongs us and we wrong them back, we have sinned. We have allowed someone else to lead us into sin, sin which we will be accountable for. When we seek revenge, we do damage to the entire body of believers. We hurt more people than just the person we are trying to hurt.
God asks us to love and forgive one another, though at times it can be difficult. We need to work together as the body of Christ, so that we can best serve God.
