Predestination

Now, in 2019, I exist.
My hands that are writing this post are formed by carbon, hidrogen, and some other atoms. I was born in 1963, so, certainly, no one of these atoms were "mine" in 1961. I daresay that most of these atoms didn't belong to my hands 3, 4 years ago.
Do I have these atoms, molecules? Do I really own my body?
Do I own my mind?
Do I know the Lord?
How do all these things happen?
The Lord decided a long time ago, that he would create the C, H, O, etc. and assemble them on my hands. He decided that he would create my brain, and that he would put "my" thoughts in it.
Do my thoughts are really mine?
I am yours, Lord.
Praise be to you because I am yours.
