And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness...
2 Corinthians 12:9
The appeal to God's sovereignty is not to foster hope that we will be spared all difficulty, but to foster confidence that when those difficulties come we are not abandoned. Things have not fallen out of hand. We can still rely on the God who has permitted us to face these things to supply us with the grace and help we need to be faithful under such circumstances.
