If we ever need to wage war against sexual sin and addiction, we should start from our thought lives because every action gets conceived there first. The stronghold is the thought of it all, not the action. The action is the result of the stronghold that is in the mind.

Listen what the Bible says:

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