I fight against temptation but sometimes it feels like temptation has a black belt.

"Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace." - Ephesians 6:14-15

Create in me a pure heart, O God, and renew a steadfast spirit within me. - Psalm 51:10

"Put on the full armor of God, so that you can take your stand against the devil's schemes." - Ephesians 6:11
