Indeed He is love...He is also Holy, righteous, justice, wrath ...
In the Jewish culture, a word was repeated 3 times to give it the emphasis ...You never see anywhere in scripture that God is "love,love,love'..but you do see that He is "Holy, Holy,Holy".. THAT is His primary attribute ...not love...
Until man understand the holiness of God and see themselves in relationship to that instead of to their neighbor, they will never understand the wrath of God against sin, they will never understand how great their need for a Savior
Oh to the contrary. Jesus said we must love God with our whole heart might and soul and to love our neighbor as ourselves. Jesus said "No greater love for a man to sacrifice his life for another". Jesus was probably telling us also He going to do just that to Save all Mankind from eternal death.
God is Holy.
