Victory is Certain if We Don't Surrender!

I was reading an article by Douglas Wilson in Credenda/Agenda magazine today, and this passage really stood out to me:

The war [between good and evil] can only be won or lost, and the only possible activities are fighting or surrendering. Given that there is only victory or defeat, we take comfort in the fact that a promise (given at the same time the antithesis was declared) said that seed of the serpent would have its head crushed, and the seed of the woman would triumph.

"The only possible activities are fighting or surrendering." This is a very encouraging idea! The idea expressed here, and borne out in Scripture, is that we can only be defeated by Satan if we surrender to him. We can and will lose battles, but as long as we confess, repent, and keeping fighting, we will NEVER lose the war! Praise God, for His mercies are new every morning!
