1. I picture him and the battles in the spiritual realm as already defeated in the Cross when Jesus died this way I don't have to worry about my future.
2. I have seen thoughts about sexual sin and immorality.
3. Both the battle cry of prayer and the sword of His Word.
Hebrews 2:14-18 NIV
 Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death---that is, the devil---  and free those who all their lives were held in slavery by their fear of death.  For surely it is not angels he helps, but Abraham's descendants.  For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people.  Because he himself suffered when he was tempted, he is able to help those who are being tempted.
1 Peter 5:8-9 NIV
 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour.  Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.
1 John 4:1-4 NIV
 Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.  This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God,  but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.  You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.
The picture below shouldn't surprise anyone who knows the Lord!
Yes, I said it! Don't worry about your battles anymore than your fears!
Greater is He that is in you then he that is in the world.
