My response to Trinitarians who argue that since God is eternally love, he must be triune is the command quoted in Mt 22:39, namely, "You must love your neighbor as yourself."
I concede that God did not become love but IS love eternally [or everlastingly] (1 Jn 4:8): love is Jehovah's essence or nature, as the "Draw Close to Jehovah" book points out. Ergo, why can't a non-created unipersonal being, who is everlasting love, love Himself prior to loving anyone else? If the unipersonal God of the Bible has
always loved Himself, then He has supremely loved the One who is worthy of being supremely adored.
And if I can become a (quasi) object by conducting a rationally inward form of discourse with myself, then why can't the unipersonal God of the Bible make Himself the supreme object by loving Himself as He loves others whom He has created? It seems to me that before I direct my affections toward a particular beloved entity (i.e. an external and
alterior personal object like my son or wife) in a scripturally proper way, I must first have proper love for myself.
