James 1-13-15
13- When tempted, no one should say, “God is tempting me.” For God cannot be tempted by evil, nor does he tempt anyone; 14- but each person is tempted when they are dragged away by their own evil desire and enticed. 15- Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death.

The Lord is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge, my shield and the horn of my salvation, my stronghold.
