"In order that Satan might not outwit us, for we are very familiar with his evil schemes." 2 Corinthians 2:11
Satan knows knows how to suit his temptations to our personal tempers and circumstances. And if, like Achilles, you have a vulnerable heel, the old serpent will be sure to strike there!
"Put on all of God's armor so that you will be able to stand firm against all strategies and tricks of the devil." Ephesians 6:11
