As Christians we can have peace and comfort knowing that God's grace furnishes to us what is lacking in our lives due to personal weakness.
Knowing Christ fills our inadequacy, we know that Christ is equal to any task we face. God is our greatest source of encouragement.
I think that this was the comfort that the Apostle Paul received in his times of trouble, when he was locked up and persecuted by some of the folks he used to hang with.
Paul gives us a new look at pur own weaknesses. We have the ability to accomplish God’s tasks by not rely on our adequacy, but on God's sufficiency.
Look at 1 Corinthians 12:1-10 (NIV). It tells the story of Paul's vision and his thorn.
In part it states, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong."
Our world boasts of its strengths and diminishes its weakness. Paul boasted of his weaknesses and diminished his strengths. God gave Paul a balanced life by putting him in touch with his own weaknesses. God allowed the messenger of Satan to torment Paul by giving him a thorn in the flesh.
Our successes are our greatest threat. Success has a way of telling us we have arrived. For this reason God allowed Paul to be humbled by his weakneses.
God's grace is sufficient without enabling us to stand-alone. If we could master our own circumstance we wouldn't need God.
God can and does use our shortcomings as well as our abilities. If we had unlimited power we would forget that we need God.
We come to the cross because of our needs.
