The first sentence of the verse is sometimes overlooked—• 'He said unto me' Paul got it from Christ. You may tell me that Christ is sufficient, but I must get it myself personally from Christ in heaven, and that will assure my heart. If we want to be delivered from ourselves, or from whatever difficulties may be in our pathway, He is sufficient. The result is, "Most gladly therefore will I rather glory in my infirmities." He besought the Lord thrice before to take away the thorn, but now a communication from Christ has altered everything; the voice of Christ alters everything. There is no third party here; it is not He said unto us, but unto me. I do not mean anything imaginative—only the simplicity of intercourse with Christ about everything in our pathway. "That the power of Christ may rest upon me." (Or, "power of Christ may tabernacle"—"Have its dwelling-place on me." J.N.D. Trans. note.) For the saint of God who walks in conscious weakness and powerlessness there is an invisible power overshadowing him all the pathway through. I believe we often try to muster up power like getting up steam, but it is in the sense of weakness that there is power.
