We tend to take ourselves way too seriously. We either feel like we can or we feel like we can't. We don't often as believers feel like we deserve to. But that's not what the scriptures teach us. In fact the scriptures teach us that being fearfully and wonderfully made means that we are not an accident.
Nothing happens by accident including disabilities and struggles.
God doesn't cause them all the time. However, at the same time it's not an accident nor does it go unnoticed. I then refer to Paul who said in 2 Corinthians, in order to keep me from becoming to arrogant God gave me a gift of a handicap to keep me in touch with my constant limitations. At first I didn't think of it as a handicap until I asked Him to remove it. My strength is made perfect in your weakness.
