Romans 12:21
Do not be overcome with evil, but overcome evil with good.
This is a command, so it is not an option. We are ordered to not let evil overcome us. How can we choose to not be overwhelmed, knocked down, or discouraged by evil? For it must be a choice since it is a command, thus we decide whether to obey or not. The strategy for obedience is given in the second half of the verse.
We are to “overcome evil with good.” God alone is good.
Mark 10:18
“Why do you call me good?” Jesus answered. “No one is good—except God alone.
Thus, we overcome evil by God. How do we practically do this? We must focus on His goodness instead of the evil circumstances. We must trust Him even when we do not understand why we are suffering. We must seek His counsel on how to respond in a manner that reflects His goodness instead of our natural desires. In other words, to overcome evil is an intentional battle plan to combat evil with the goodness of God.
Is this easy? No. However, it is commanded for our benefit. God wants to protect us from being knocked down by evil. He wants to work through us so that evil is vanquished. The Lord does not want evil to prevail against us. The only way for us to not be consumed by the evil is to conquer the evil. The goodness of God is the assured victory over all evil!
Whatever evil situation that has risen against you is now your opportunity for victory! When you stand in the goodness of God, the enemy not only cannot knock you down, he also loses ground against you. The evil is overcome and the flag of goodness is placed up as the victory. In your difficulties, get the battle plan from God. His goodness will win!
