1. Walk by faith (5:1-8). It is important to take note of what it means to live by faith. All too many people think on that phrase as a sentiment that does not correspond to biblical teaching. Many believe that to walk by faith is to walk with a genuine spirit of good will, believing in God because he is a God of love, and trying to live in accordance with what one thinks is right. Though this has a commendable quality, it is short of the biblical idea. To walk by faith is to trust in the Lord, hearing His word, and making application of His will to one’s life, it is to obey God’s commands (Romans 10:17; I John 1:5-7).
2. The love of Christ compels (5:9-15). With the mission the Lord gave Paul (and others), he knew well that if one did not heed his message, the terror of the Lord will be more than one bargains for; in fact, it is deadly! Because Paul had such a vivid picture in mind, he preached. He preached not only because of the vivid picture, but he preached because the love of Christ compelled him. Note how the love of Christ is related to knowing the terror of the Lord.
3. Don’t know – according to the flesh (5:16-21). It is very hard to change one’s pattern of thinking. For most, we think in accordance with the flesh – that is, we think in accordance with a fleshly standard. Paul said that he no longer did that, but he thought in accordance with a new standard, and those in Christ live by a new standard. If each of us do this, think how much better, how much easier, and how much charity will be extended to the next person.
