For Thou didst form my inward parts; Thou didst weave me in my mother’s womb. I will give thanks to Thee,
For I am fearfully and wonderfully made. Wonderful are Thy works, and my soul knows it very well.
My frame was not hidden from Thee, when I was made in secret, and skilfully wrought in the depths of the earth.
Thine eyes have seen my unformed substance ; and in Thy book they were all written, the days that were ordained for me,
When as yet there was not one of them. Ps 139.13
So these words do not apply to Jesus as he was already pre existing?
Silly. Scripture doesn’t contradict if it is true. If you cannot make all scripture work in your view, then your view is wrong. And if you cannot understand other people’s then pray for understanding. Thinking you understand someone’s view and criticising them based on your own misunderstanding means you need to change.
