Everyone gets old. And because we are old we feel more and more pain in our weak body. But for the Christian there are some benefits to having a weak body. Here are five benefits derived from the above passage:
1. Others will see that any power we have is not of us (2 Cor. 4:7-10). God has shone His light “in our heart to give the light of the knowledge of the glory of God in the face of Jesus Christ” (v. 6). This light and power that shines in us, Paul said, is a treasure, a treasure that is held in earthen vessels. Paul was speaking of our bodies—which are weak, that is, temporary and very susceptible to disease and decay. But the thing about our weak bodies that is a huge benefit, particularly for the salvation of others and for the kingdom of God, is that it makes it obvious that the power of God in us is not generated from us, but from Him.Also, I think, since our bodies are weak and may have cracks in them, as an old clay vessel would, if we admit and boldly proclaim our weakness in humility, this makes it even more probable for others to see the light of Christ shining through the cracks in our exterior. Hence, I think the weaker our bodies are, and we are transparent about who we are, the more likely it is for anyone to see the glorious light of Christ shining through us.
2. Others can receive eternal life through us (2 Cor. 4:11-14). There is nothing better in bringing someone to Christ than to allow him or her to hear our testimony and to allow them to see how Christ has transformed us and how He shines in us. A testimony is particularly powerful when we humbly admit our weakness in contrast to His strength.
3. God will receive more glory (v. 15). As God’s grace brings more and more people to Christ through out human weakness, God will receive more and more glory.
4. Spiritual renewal (vv. 16-17). Though our bodies are weak and dying, our spirits are being renewed every day. This reality becomes more and more apparent as one gets older.
5. We look forward to the joys to come (v. 18). This is a huge benefit. The more we see our weakness, the more we look forward to what is unseen. In fact, those unseen things become more and more real to us—especially if we are abiding in Christ.
