Instead of condemning each other, decide not to do anything that might lead your fellow believer to sin by following your example and which would then cause others to speak evil of you.
13 Since it is God who will judge everyone, we must stop saying that God should punish some of our fellow believers! Instead, you/we should decide that you/we will not do anything that would be an example that might cause fellow believers to stop trusting in God [DOU]. 15 If you eat food [MET] that anyone for whom Christ died thinks that it is wrong to eat, that person might be encouraged {you might be encouraging that person} to do something that he believes is wrong. As a result, you might cause that fellow believer to stop trusting in God. In that way he would be ruined spiritually just because you have stopped behaving as one who loves others should behave! 17 Letting God rule our lives [MET] does not mean that we must obey regulations about eating or drinking something! Instead, it means we must live righteously, act peacefully towards others, and be joyful by the power of the Holy Spirit.
