Any private "revenge", even if the starting point is "justice", will eventually deviate from God's will if the means are corrupt. What we can pursue is process justice and leave the results to God.
However, Christians are not passive, let alone silent. In this case, Christians should continue to speak out for justice and constantly influence society. Proverbs 31:8-9: "Speak for the dumb, for all the lonely. You should open your mouth and judge righteously, and defend the poor and needy. "
Therefore, even if you are destined to lose the case, you can leave a testimony and influence to inspire those who come after you. What may seem like a failure to people may be a seed in God's hands, bearing the fruit of justice in the future.
Even if you have no hope of getting justice for yourself, you must persist, so that you can still fight for others. Churches need to support each other. At the same time, they can also use the media, communities, church organizations, Christian lawyers, international organizations, etc. to expand their influence.
Because, "We do not fight against flesh and blood, but against the rulers, the authorities... the spiritual evil spirits in the heavens. ”Ephesians 6:12
We certainly cannot give up the fight, let the devil run rampant, and let the devil's followers fill the society.
We can be tired, but we should not give up standing up for justice. We can be powerless, but believe that God is still working to make us strong and courageous.
