One of God's most precious gifts to us is friends who encourage us and lovingly challenge us. According to scripture, a friend is one who challenges you to become all that God intends.
The mark of biblical friends is that their friendship draws you closer to Christ. They 'sharpen' you and motivate you to do what is right. It is equally important to examine the kind of friend you are to others. Strive to be the kind of friend that helps others become more like Christ.
