4 Then the word of the Lord came to me, saying:
5 “Before I formed you in the womb I knew you;
Before you were born I sanctified you;
I ordained you a prophet to the nations.”
This is when God first spoke to Jeremiah; letting him know that he was set apart to be a prophet of the Lord.
But Jeremiah felt unworthy of the position, stating his youthfulness. Jeremiah 1:6
However, the Lord told Jeremiah not to be afraid, because He will be with him. The Lord told Jeremiah that He would give hime the words to speak. Jeremiah 1:7-8
Just as the Lord knew Jeremiah before he was even born, He knows us as well. God created us each with a purpose in mind.
10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
When we trust in God, He will tell us where we need to go and give us the words to say. However, it is up to us to go where He leads us and say what He’s given us to say.
