Pay close attention to verse 14: “and THAT my soul knows VERY well.” Does your soul know that very well? I certainly hope so. Please know this!
13 For You formed my inward parts;You covered me in my mother’s womb.
14 I will praise You, for I am fearfully and wonderfully made;
Marvelous are Your works,
And that my soul knows very well.
15 My frame was not hidden from You,
When I was made in secret,
And skillfully wrought in the lowest parts of the earth.
16 Your eyes saw my substance, being yet unformed.
And in Your book they all were written,
The days fashioned for me,
When as yet there were none of them.
I promise you this will pay dividends in the long run. What are you waiting for? Get to it.
