Is it enough?

But he said to me, "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.
2 Corinthians 12:9 (New International Version)

My grace is enough; it's all you need.
My strength comes into its own in your weakness.Once I heard that, I was glad to let it happen. I quit focusing on the handicap and began appreciating the gift. It was a case of Christ's strength moving in on my weakness.
2 Corinthians 12:9 (The Message)

I guess so.
But I need to understand this better practically.
