God, who in HIs essence is love, has called on people to love one another according to His love for them. God, in His nature, is love. God's greatest act of love has been giving of Himself to us in Christ Jesus. Jesus took on flesh, suffered and died, and rose again to forgive the sins of all who trust in Him. Jesus work leaves no question of God's glory and His love for His people. Because God, out of His great love, has sacrificed of Himself for us, we are to love others and sacrifice greatly on their behalf.
