The Bible tells us that love is grounded in the moral nature of God, Himself. It affirms we know love by its moral behavior:
"By THIS the LOVE (agape) of God was MANIFESTED IN US, that God has sent His only begotten Son into the world SO THAT WE (those who return His love) might live through Him.
I John 4:9
The Bible maintains that Love is behavior grounded in morality. God, because he is LOVE and because He is Just, is willing to rescue the person who repents of his sins from the consequences of living in a cursed and dying world.
Paul teaches in Romans that God's love and justice has the same source, God's nature.
"... for the demonstration, I say, of HIS RIGHTEOUSNESS at the present time, that He might be JUST and the JUSTIFIER OF THE ONE who has faith in Jesus." Romans 3:26
~~Jesus teaches that what is evil and what is right are opposing forces~~
"For everyone who does evil hates the light, and does not come to the light, lest his deeds should be exposed." - John 3:20
"But he who practices the truth comes to the light, that his deeds may be manifested as having been wrought in God." - John 3:21
