No one is born again or enters God’s kingdom without getting the Spirit of God (the Holy Spirit). You must be born again; your eternal life depends on it.
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?
