I did not bring up such a thing as "God's love," which seems a different subject. I am alluding to this which was the basis for saying "If I love people a lot then I am more likely to have some love for God, but if I don't love people it is certainty that I don't love God."
But God is not a man, so feeling the love of God is not the same as feeling love from people. It is abstract, and you don't feel it which is part of the problem. God's discipline is another way of describing God's love. So if you are hurt that is God loving you, from a certain point of view. This is not an easily accepted kind of love. It is more alien than human.
[1Jo 4:19-21 NIV] 19 We love because he first loved us. 20 Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen. 21 And he has given us this command: Anyone who loves God must also love their brother and sister.
Life lived under the law is intended to aid a male in developing spiritual attributes which we call spiritual fruit, such as patience and peace. Psalm 19 is a song about how great the law is at converting the heart. How does a male person like me get over an offense like what happens when his family is attacked and harmed or when his livelihood is taken? What about when we are mistreated by others, and over time we start feeling resentment? We don't get over it, because our hearts pour out venomous foam. Unless we are regenerated continually we express evils. Even if we haven't been harmed we daydream about the heroic act of revenge or unheroic acts of domination and cruelty. Any and all evils come from the human heart. According to the Psalms the law helps with this, and so its not good to talk about it like its a bad thing. Also its not performed under one's own strength but in a tightly knit community, usually.
