Isaiah 44:24; “Thus saith the Lord, thy redeemer, And he that formed thee from the womb, I am the Lord that maketh all things; That stretcheth forth the heavens alone; That spreadeth abroad the earth by myself.”
“Indeed, you and I have a plan to guide us in our lives—the eternal plan that was given to us in the premortal world and that will bring us back into the presence of our Heavenly Father.” – Robert D. Hales
Jeremiah 1:5; “Before I formed thee in the belly I knew thee, and before thou camest forth out of the womb I sanctified thee; I have appointed thee a prophet unto the nations.”
Psalm 139:13-16; “For thou hast possessed my reins Thou hast covered me in my mother’s womb. 14 I will praise thee; for I am fearfully and wonderfully made: Marvellous are thy works; And that my soul knoweth right well. 15 My |substance was not hid from thee, When I was made in secret, And curiously wrought in the lowest parts of the earth. 16 Thine eyes did see my substance, yet being unperfect; And in thy book †all my members were written, Which in continuance were fashioned, when as yet there was none of them.”
God’s word says nothing about our souls living in a pre-existent world. However, God does tell us that we are unique in our creation, and our souls began at conception.
From His word we also know that our souls can become eternal, but it only happens when/if we believe in the God of the Bible!
Matthew 25:46; “And these shall go away into everlasting punishment: but the righteous into life eternal.”
Ecclesiastes 12:7; “Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.”
