IS against his nature, and so also God's.
OMG TAMMY! Wrap your brain around this:
However, you may purchase male or female slaves from among the foreigners who live among you. You may also purchase the children of such resident foreigners, including those who have been born in your land. You may treat them as your property, passing them on to your children as a permanent inheritance. You may treat your slaves like this, but the people of Israel, your relatives, must never be treated this way. (Leviticus 25:44-46 NLT)
That is what is Divine Law, God's Will or Commandment, His NATURE (as you say) as expressed by YHWH in the Torah.
That is YHWH giving EXPLICIT PERMISSION to practice SLAVERY, just like He gave man permission to eat animal flesh after the Flood.
THAT IS LEGALIZATION OF SLAVERY: NOT PROHIBITION, BUT LEGALIZATION OF SLAVERY!!!
Jesus endorsed EVERY LAST WORD OF THE TORAH, including the legalization of SLAVERY, whether he singled it out or not!!
If you deny it, you are truly beyond hope: you cannot even listen or comprehend YHWH's own words, which even Jesus commands you to study in order to know His Father's message of "love".
