Leviticus 18 we see why Noah shamed his son in Genesis 9. The Beginning of the Bible gives us great detail of what God loves and what He hates that never changed. He gave us a One Time Sacrifice in the Blood of Jesus , that Sacrifice did not change what God loves and hates. Read chapter 18 understand the system God set up. Verse 21 And you shall not let any of your descendants pass through the fire to Molech, nor shall you profane the name of your God: I am the Lord.
A relationship of any kind we try and understand what that person loves and hates. There is not a more important relationship in our life time , than the one we have with God.
