Chapters 1-7
Paul describes the characteristics of an Apostle. He explained that his ministry was to preach the words of Jesus Christ and not himself, “For we do not preach ourselves, but Christ Jesus as Lord, and ourselves as bondservants for Jesus’ sake” (4:5).
Paul then explains that Christians will suffer. "We are afflicted in every way, but not crushed; perplexed, but not despairing; persecuted, but not forsaken; struck down, but not destroyed.” It is promised to followers of Christ that they will suffer. Paul states that compared to eternity with Christ the sufferings of this world are temporary and have a purpose for us. "For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal."
Here the element of suffering is discussed and explains that everything will come full circle. This is important to note because Paul is reiterating to everyone to never give up despite how difficult everything may appear and the internal struggles that we all go through.
