The power of resurrection life takes all strength from Satan: "He that is begotten of God keepeth himself, and that wicked one toucheth him not." 1 John 5:18. In our earthly life, the flesh being in us, we are exposed to the power of the enemy, and the creature has no strength against him, even though it should not be drawn into actual sin. But if death is become our shelter, causing us to die unto all that would give Satan an advantage over us, what can he do? Can he tempt one who is dead, or overcome one who, having died, is alive again? But, if this be true, it is also necessary to realize it practically. "Ye are dead.... Mortify therefore." This is what Gilgal means.
