The fact that God is love, necessitates a inter-trinitarian God. If that is his nature he must love another and not Himself. So He is either a trinitarian God or there is a co-eternal creation that he has always loved. Creation certainly has not always been.
What makes Christian love different then other kinds of love?
Answer: The love for the ungodly, ugly, and the unlovely. We love our enemies.
But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? You therefore must be perfect, as your heavenly Father is perfect.
God loves the good, needy, near and far. His scope should be our scope. The Father presses the image of His Son into us through His Spirit.
Since God is love and is immutable nothing we can do can change His nature. Therefore there is nothing any of His creatures can do to not make them objects of His love. Again, we are loved because He is loving. We love because He first loved us. Our God’s love is what makes a Christian’s love unique in the world.
