Wisdom is better than weapons of war: but one sinner destroyeth much good.
A little leaven leavens the whole lump (Gal. 5:9). 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 in a spiritual war.
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.
Loving Father, please give me wisdom to see through the deceptiveness of the devil's schemes while I seek to live your truth and display your character in my life. Thank you for your power at work in me and in my life. In Jesus' name I pray. Amen.
