But he said to me, “My grace is enough for you, for my power is made perfect in weakness.” So then, I will boast most gladly about my weaknesses, so that the power of Christ may reside in me. – 2 Corinthians 12:9
When the Apostle Paul wrote this, there were things in His life that were causing him pain or making him feel weak. Whether these were physical or emotional, or some outward problem we are not told. But in the verses before Paul says he has prayed for them to be taken away, but God has allowed them to remain for a reason. The reason is to demonstrate God’s grace.
We might like for things to always go smoothly for us, for God to always immediately fix our problems and take away our aches and troubles. Often, in His love, he does take these things from us. But He also may allow thing to remain in our life in order for us to continually realize He is the source of our strength. We can face all things, not because we have any kind of power ourselves — in fact, as Paul says, we are weak; but because God’s power and grace is more than enough. His power becomes all the more visible, because we can face problems that are impossible for us to deal with ourselves, and through Him we overcome them.
We can actually be happy about our frailties, because it is through them we recognize the grace and love of God. Whatever it is that burdens you, makes you feel helpless, or causes you distress are all leading to the overwhelming power of our Father. All of these things are temporary, and will soon be gone. But through them we come to know God’s perfect power.
