I invite you to resume our studies together in the book of Acts. We will look at the twelfth chapter -- a very exciting passage. I am sure that you had not been a Christian for very long before you discovered that the enemy with whom we wrestle has a very disconcerting way of striking when everything seems to be going well. Just when you think the path has smoothed out and that you are having a great time in the Lord, with nothing but blessing ahead -- then everything seems to fall apart at once. That is confirmation of what the Bible tells us is the truth: We are not wrestling against flesh and blood, but we are engaged in a life-or-death struggle against principalities and powers and wicked spirits in high places, who are able to unleash a vicious, lashing attack against us -- just when we think things are going well.
