The point of Total Depravity is that, until you are born again, until you have been washed with the blood of Jesus, you are totally depraved with no desire for God, no desire to please God, and with no ability to go to God. That is the total depravity of man in his natural state. In other words, there is no Holy good in him UNTIL he is born again.
Now, let’s take your scenario... a child, totally depraved by his parents, completely ignored by them. Now, suddenly, an adoptive parent takes him, cleans him up, loves him like no one ever has, takes care of him and let’s him live with the parent forever. That is the Lord with those he chose. We (and I am including you in this, because I can see in your nature that you love the Lord)having once been lost, wallowing in the mire of sin, have now been washed with the blood of the Lamb, adopted into the family of God, and will live with him, forever.
Well.. I think you don’t believe in total depravity of calvinism, because total depravity taught by Calvin teaches that people are by nature not inclined to love .
God created us out of love and for love.He wills us to love.I don’t think you believe that God wills ANYONE to hate?
Dear Brother,your scenario is excellent, because it shows that the adaptive parents followed the will of God “freely”.
God worked in union with the adaptive parents human nature because of their desire follow the will of God.
When we humble ourselves to the will of God(that is always for the purpose of love) We become participants in the love of Jesus Christ
