The Christian life is a fight, a struggle, a warfare. And our opponent is Satan. He is the adversary of God’s people. While he has succeeded in making some people question his existence, he is definitely alive and well on planet Earth today.
As Christians we are not to be ignorant of his techniques lest he should get the advantage of us (2 Corinthians 2:11). Satan has used four tactics since the beginning of time that we need to be aware of.
