As iron sharpens iron, so a friend sharpens a friend.
A good friend should sharpen you. With the forever goal of causing you to improve, a friend should hold you accountable to doing what is right and staying true to your faith. She should push you to go further, deeper and higher. She should love you for you and encourage you to be who God has called you to be. She should walk with you, but when the time is right be willing to speed things up and encourage you to run. A friend who only agrees with you and goes along with everything you say and do, although easy and comfortable, isn't always what is best for you.
As you begin the new year think on your friendships. Who is a friend that sharpens you? Who do you sharpen? In what ways would you like to change your friendships this year?
