The foundation of peace and unity in the Body of Christ is unconditional love from one believer to another. If we don't know what it really means to love people, we'll sow discord in our community and make unity in the church impossible. Love is the bond of perfection (Colossians 3:14). Love is the foundation of obedience, purity, and holiness. If we cannot love people, we cannot say we have fellowship with God.
