Its one thing to suffer because of foolish choices. Its a different kind of suffering when it comes in the midst of serving God. Jesus learned obedience by those things which He suffered. The first thing God did after baptizing Jesus in His spirit was lead Him into the wilderness to be tempted by Satan.
Struggle is a sign of life.
Dead men have no struggle.
The fact that you are struggling is proof you haven't been defeated! There is a special intimacy created (the ability to know Jesus more) when we choose to continue walking closely with and trusting Him in the midst of our struggle.
