Is it possible to maintain a hopeful or positive attitude? It really depends on you. It is your choice—your decision; in everything choose to stay positive.
Did you consider believing that the devil could steal from one of God’s children is an insult to God. God is our father, we are His children, He knows all things (1 John 3:20; Psalms 139:1-6, 147:4-6; John 2:24-25; Hebrews 4:11-13) and sees all.
So He knows when the thief—your thief (if you believe the devil is the thief)—the devil is coming to steal. Why would your Father not stop him?
