Paul expands on the difference in attitude and lifestyle that he, Apollo, and Peter have as compared to the Christians in Corinth. They have given up all their earthly possessions and now they do not have an extra set of clothes nor a home of their own here on earth. They work hard physically so that they will not be a financial burden on the new converts. They respond to cursing, persecution and slandering with blessings, kindness and patient endurance. They are willing to be treated as the lowest form of life here on earth so that God might be glorified. Is it necessary for all of us to go through this kind of treatment? No, but we must have the attitude and the willingness to do it, if that is what Jesus calls us to do.
3 Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; 4 perseverance, character; and character, hope. 5 And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us.—Romans 5:3-5 NIV
18 I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.—Romans 8:18 NIV
