Then the word of the Lord came to me [Jeremiah], saying,  Before I formed you in the womb I knew [and] approved of you [as My chosen instrument], and before you were born I separated and set you apart, consecrating you; [and] I appointed you as a prophet to the nations.  (Jer. 1:4-5).

He planned things for me in the future before the earth or time existed (I Cor. 2:7).

He had made plans for my life to give me His grace before I was born (Gal 1:15)

He chose me and called me to redemption to be saved and be made holy (Eph 1:4).

He chose me before my birth to bless me and save me through Christ (Eph. 1:3-4).

He planned my adoption prior to my birth (Eph. 1:5).

And according to His good pleasure, He revealed the secrets things of God to me (Eph.1:9).
