Just a little leaven and the whole lump is changed. A sinful person can have the same effect on a whole group of people committed to God. So let's be wise and reverence God by obeying him and his Word. Let's be insightful in the way we deal with sin and temptation in our lives. Also, let's be sure to remember that we are at war with the evil one. Then let's praise God, because our Savior has already defeated our enemy and the Holy Spirit empowers us to stand up to Satan's attacks and resist his temptation.
