We all are tempted! But none of us has to sin!

You are not evil because you are tempted! We all are tempted, sometimes every hour of everyday. God wants us to know, "4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ..." (2 Corinthians 10:4-6) If we don't take those thoughts captive, we are in trouble, and may end up sinning. Let's really think about every thought, run to Christ with it each time. It will also deepen your relationship with Him!
