An opportunity for victory. Victory only comes in battle. Without a battle, we could have no victories in our Christian life. The good news is, we are guaranteed a victory in every battle we face. An opportunity for growth.
Maturity comes through struggles.
This is true both in our natural lives and in our spiritual lives. We hate to see our own children have to go through struggles in life, but we know it is the only way for them to grow emotionally as well as physically. An opportunity to glorify God. The greatest use of faith is in the struggles of life. Faith is a weapon against Satan.
