I think that's an accurate reflection of some Reformed thinking.
However it leads to equating man with "everything else" and God as responsible for our choices and sins. There is not a hierarchy of being only a dualism. It leads to looking at ourselves the same as a dog or a tree and works against the truth of relationship - with each other, with the Church, with God.
So while it sounds good on quick hearing, but when we end up in such a place, we realize: somewhere we've made a wrong turn.
Why did God make man?
Nonsense. If we belong to God, we belong to God. As His children, we are loved by Him so much He sacrificed His Son for us.
"Now thanks be unto God, which always causeth us to triumph in Christ, and maketh manifest the savour of his knowledge by us in every place. For we are unto God a sweet savour of Christ, in them that are saved, and in them that perish: To the one we are the savour of death unto death; and to the other the savour of life unto life. And who is sufficient for these things? For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ." -- 2 Corinthians 2:14-17 "Faithful is he that calleth you, who also will do it." -- 1 Thessalonians 5:24
My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand." -- John 10:26-29"But ye believe not, because ye are not of my sheep, as I said unto you.
No canines anywhere around.
