From the Today God Is First devotionals (http://www.todaygodisfirst.com/):
'So often, when God places a call on one of His children, it requires a separation between the old life and the new life. There is a time of being away from the old in order to prepare the heart for what is coming. It can be a painful and difficult separation....
Perhaps God has placed you in your own desert period. Perhaps you cannot make sense of the situation in which you find yourself. If you press into God during this time, He will reveal the purposes He has for you. The key is pressing into Him. Seek Him with a whole heart and He will be found. God may have a special calling and message He is building in your life right now. Trust in His love for you that He will fully complete the work He has started in you.'
Winners stay strong and persevere even in the midst of a desert of preparation.
