Jehovah created humans in His image, which means His qualities which includes justice. God see the injustice done to His creation and He has set a time to bring vengeance upon those that cause tribulations to fellow humans. In the meantime we are told not to take matters in our own hands because vengeance belongs to God alone, but to pray for strength and courage to endure.
Vengeance is mine, and retribution,At the appointed time when their foot slips,For the day of their disaster is near,And what awaits them will come quickly.’
Do not avenge yourselves, beloved, but yield place to the wrath; for it is written: “‘Vengeance is mine; I will repay,’ says Jehovah.”
Rejoice in the hope. Endure under tribulation. Persevere in prayer.
