“Iron sharpeneth iron; so a man sharpeneth the countenance of his friend,” Proverbs 27:17 tells us. God uses Christian friendships to help His children grow in grace and stay true to Christ. But our twenty-first-century Western culture values individualism, busyness, and selfishness—qualities that do not encourage deep, long-lasting, satisfying friendships. The authors guide us through a practical survey of biblical and historical friendships, drawing principles from them that will aid us in forming our own biblical friendships that will sharpen us for our Christian journey in a world that is no friend to grace.“A treasure! From two of my friends, a booklet about friendship that makes me thankful for them and what they have written. Friendship is what Jesus gifts in His final hours—‘you are my friends’—and discovering friendship with others is one of God’s great gifts. Winsomely thoughtful and practical, this is a rare treasure that is bound to be read widely.” — Derek W. H. Thomas, senior minister, First Presbyterian Church, Columbia, South Carolina; Robert Strong Professor of Systematic and Pastoral Theology, RTS Atlanta
