True talk @deathlyhorror
Just to add to what you have written, another reason why we should count it all Joy when we fall temptation is:

1. It makes us see Grace at work in our lives.
   Paul said 2Cor 12:10: "Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong."
2. Every trial and temptation comes with a lesson and these lessons are needed for younger believers or believers who haven't gone through that dealings.

2Cor 1:4: "Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God."
I pray that we would see through that which the Lord is taking us through. Selah
