"For by him [Jesus] were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him" (Col. 1.16).

So if you remain a Mormon you are purposefully rebelling against God of the Bible. Jesus existed before time and space with the Father and the Spirit. There is none beside the Triune God, before Him or after Him.

Have the humility to repent and accept the One True God of the Bible. Mormonism is a great sin, a sin that will eternally separate you from God because you will never repent.
