Paul was divinely commissioned to proclaim the glorious all-sufficiency of Christ’s redemptive work. He made known God’s offer of salvation by free grace to all who trust in Christ, along with their heavenly position, blessings and prospect in Christ.
Lest he should become puffed by the glory of these great truths, God gave him what he called “a thorn in the flesh,” an aggravating physical illness of some sort. “For this thing,” he says, “I besought the Lord thrice, that it might depart from me.” (2 Cor. 12:8). But the Lord knew better than Paul what was good for him, as Paul continues in verse 9; “And he said unto me, My Grace is sufficient for thee: for my strength is made perfect in weakness.”
How right God is! Every Christian knows that with brimming health and “good fortune” comes the tendency to forget our need of Him, while infirmity causes us to lean harder and to pray more. This is where our spiritual power lies. Every believer should acknowledge this and say with Paul: “Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities…for when I am weak, then am I strong.”(vs. 9 & 10)
