Don't Dwell in Temptation
Temptation is unavoidable, but we shouldn't dwell in it.
For example, you might look at a woman (in lust), and then you continue to stare at her.
The first glance you can't help, but continuing to look is what becomes sin.
It's important to remember that with any temptation, God will provide an escape.
There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
- 1 Corinthians 10:13 (KJV)
But you can't do it yourself, you need to ask God for help.
I can do all things through Christ which strengtheneth me.
- Philippians 4:13 (KJV)
And then the victory is yours.
Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
- 1 John 4:4 (KJV)
