Love changes everything, especially what we think of our own privileges. In this last sermon on Christian unity, we see that more mature believers bear a special burden to ensure that this loving unity is maintained. Since they are strong, they can powerfully deny their freedoms for the greater good of the church. The solution is not legalism or fundamentalism, but a harmonious group of people covenanted together around the truth and doing all they can to neither condemn not cut off each other. This kind of harmony brings glory to God.
