Romans 12:21 is a verse from the New Testament of the Bible, which reads:
"Do not be overcome by evil, but overcome evil with good."
This verse comes at the end of a passage in which the Apostle Paul encourages Christians to live a life of love and service to others, putting aside their own selfish desires and ambitions. In this particular verse, Paul is reminding believers that they will face evil in the world, but they should not let it conquer them. Instead, they should respond to evil with good, showing love and kindness even to those who have harmed them.
The message of this verse is an important one for Christians and non-Christians alike. It encourages us to resist the temptation to respond to hate with hate, violence with violence, or wrongdoing with more wrongdoing. Rather, it invites us to choose a better way, to seek reconciliation and forgiveness, and to work for the common good. Ultimately, it reminds us that love and compassion are more powerful than hate and division, and that goodness can overcome even the darkest of evils.
