For my own audience, I would address the issues by first dividing up my passage based on its paragraphical form. The three paragraphs making up the passage would form the basis for my main points. On the basis of verses 1-4, my first main point would have to do with identifying the real problem at hand. The text itself implies that while division in the church is a problem, it is actually symptomatic of a deeper problem of spiritual immaturity, or carnality. I would mention the many heartfelt sermons I've heard and books I've read calling the church in vain to a vague, indefinite sort of unity. I would suggest, therefore, on the grounds of verses 5-9, that genuine Christian growth and solidarity cannot be based on a human personality, not even my own self. Humans all have one thing in common, according to Paul - they are nothing in themselves, since all they have and all they achieve derives from the grace of God. Unity must be based on a common Christian understanding of what is really most important. This would lead into my final thought, from verses 10-15, that despite the many and substantial differences among Christians, we are actually defined by one common belief - that Jesus is the foundation of our faith. A Christian at bottom is a believer in Jesus Christ. Apostles, pastors and teachers come and go, but Jesus is our ultimate authority. This thought could be extended beyond the question of church authority to matters of circumstance, money, ministry, success, family, and ultimately, eternity. Putting our faith or hope in anyone or anything besides the risen, living Christ is really an act of the flesh. On the other hand, a foundational faith in Jesus Christ is a true expression of the Spirit, and brings a proper perspective to critical issues of salvation, ministry and growth in the kingdom. I would then make a final appeal to live with an eternal perspective. If everything associated with this world is destined to burn, as Paul assures us, the highest expression of faith would be to begin examining our work and building our lives on the foundation of Jesus Christ for the world to come.
