The inside measurement of our standard railway track is 1435mm with a tolerance of plus or minus 10mm. This means that a certain degree of tolerance is correct but there are limits beyond which it is dangerous to go. The Bible says, “If it is possible we should live peacefully with people.” [Romans 12:18] But we must be careful not to be so tolerant that by our silence we allow someone to think something is right when it’s wrong. God exercises a zero tolerance policy towards sin which means that if we committed only one sin this would keep us out of heaven! This is because heaven is infinitely pure and must not on any account be defiled.
