“Before I formed you in the womb I knew you ,before you were born I set you apart; I appointed you as a prophet to the nations.”
This reminds me of Ephesians 2:10, For we are God’s workmanship, created in Christ Jesus to do good works , which God prepared in advance for us to do.
Whether Old Testament or New, the truth is this: God knew us before we were born, formed us in the womb, set us apart for Him, and planned the work we would do for Him. He encourages us: don’t be afraid to speak, be ready, and remember “I am with you”(vs 8).
