Apostle John affirms that "God is love" ( 1 John 4:8 ). God does not merely love; he is love. Everything that God does flows from his love
Romans 5:8 says ". . .commendeth his love toward us, in that, while we were yet sinners, Christ died for us." The lost sinner living in rebellion and sin is still loved by the Lord. He loved us enough to die for us and pay our sin debt while we were sinning against Him. This shows that true biblical love is a matter of will....not of emotion. God choose to love us and His love was not based on our meriting it in any way.
"Agapao" This word is a verb used to describe God's divine love. The noun is "apape." Example is John 3:16, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." (John 3:16) This is the action of totally being committed to the well being of others without regard for their worthiness even unto death. That love was demonstrated by Jesus when He suffered and died for our sins. We, as Christians, are to show that unselfish love to others.
