Following are a number of back-translations of Romans 3:25:

• Uma: “According to God’s plan/command, Yesus was killed and his blood was spilled. God did that so that Yesus was punished to pay-for/redeem the sins of mankind, so that he would forgive our sins if we believe in Yesus. Before Yesus died, God did not punish the sins of man. He let-be [i.e., did nothing about] the sins of man for the time being, because of his patience. But if he never punished sin, he would not be just. So, with the death of Yesus, God showed that he was upright.” (Source: Uma Back Translation)
• Yakan: “Isa Almasi was sent here by God in order to die and that his blood be spilled, and because of that death of his, the sin of human beings/mankind is forgiven if/when they trust him. God did this demonstrating/showing that he is really straight. Formerly God endured the doings of people and it was as if he just did not do anything (about) their sins.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “God sent him so that he might become a sacrifice in our (incl.) place, and because His blood flowed, God will forgive our (incl.) sins if we believe in Him. God did this so that we might understand that His judgment is righteous, even though long ago, because He was long-suffering, He did not for awhile yet punish people because of their sins.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “God sent him to die so that he would thus pay-for/undergo the punishment of our sins, and by-means-of his blood, our sins can be forgiven if we believe in him. God did that in order to show the righteousness of what he had done previously. Because previously, he had been bearing-with people’s sins, not punishing them immediately,” (Source: Kankanaey Back Translation)
• Tenango Otomi: “God sent Christ in order to die before the face the eye of the people. He died in order to clear the sins of all people who would believe in him. When Christ died, it was seen why it is that people had been cleared of sin. In past days, God endured the people patiently, he didn’t send punishment for the sins they had done before.” (Source: Tenango Otomi Back Translation)
• German New Testament translation by Berger / Nord (publ. 1999): “God used the violent death of Jesus as an opportunity to make Jesus Christ the public place of forgiveness for everyone. In this way, God proved that he himself is righteous by forgiving the sins that people had previously committed. This forgiveness is granted to the individual by believing in Jesus as its mediator.”
