The Apostle Paul is asking the believers to give space for each other to grow in the grace and knowledge of the Lord Jesus Christ. Be not quick to be offended by the difference in preference that each has. He has cited the examples concerning the food that they choose to partake. He asked that Christian grace be exercised. He has asked the believers to exercise forbearance for the weak brother who choose to eat only vegetable and will not take meat. As William MacDonald said well, “Let this be not a test of fellowship.” Do not allow such matters to hinder Christians from relating to one another. To “set at nought” is to devour one another with unkind words because of such differing practices.
