And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me–2 Cor. 12:9.
When Paul was given a special messenger of Satan to buffet and beat him down in the flesh he asked the Lord Jesus Christ for immediate relief (2 Cor. 12:8)). Instead of removing the thorn in the flesh, the Lord in His infinite wisdom instructed and encouraged Paul that His grace was sufficient or enough to sustain him in the time of trial.
Surely this is true for all of the Lord's people, although we often think in our time of despair and doubt that there is no way we can survive our trouble, heartache, grief and pain. Yet, the answer of the Lord is always the same, "my grace is sufficient." His grace is sufficient to choose us unto salvation (Eph. 1:3-6). His grace is sufficient to save us by His mighty power (Acts 15:11; 2 Tim. 1:9). His grace is sufficient to keep us from falling (1 Peter 1:5; Jude 1:24). Surely, His grace is sufficient to sustain, comfort and bless us in the time of trial (Isa. 41:10; 43:1-7; John 16:33; Rom. 8:28).
The essence of this is that the Lord Jesus Christ is sufficient, He is enough, "Christ is all and in all" (Col. 3:11). The Lord's salvation and strength is perfect and complete at all times but especially in and for our time of need and weakness (Psalm 46:1; Phil. 4:19). He instructs us to come boldly unto His throne of grace. Why? The Lord's grace is sufficient. Read this precious promise found in Heb. 4:16, "Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need."
The Lord Jesus Christ is our all-sufficient Saviour. He does give us daily grace and daily strength for each trial. We realize and appreciate this the most when we know and confess our own weakness, frailties, inabilities and sinfulness. Paul says, "Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong" (2 Cor. 12:10).
