Messages for Exaltation, For the Sunday Schools of The Church of Jesus Christ of Latter‑day Saints, Gospel Doctrine Class, pp. 378‑379; “[Jesus Christ] was willing to make payment because of his great love for mankind, and he was able to make payment because he lived a sinless life and because he was actually, literally, biologically the Son of God in the flesh.” – First Presidency
John 1:1; “In the beginning was the Word, and the Word was with God, and the Word was God.”
Jesus was in heaven with God because. Why you ask? Well, it’s because He is God. It’s not because He was given birth to. And it’s not because God created Him. He was there and always had been. No sex. No other explanation needed. He’s God.
To try and explain why Jesus paid for sin with His life other than what’s already been revealed to us in the Bible is a lie; aka false prophecy!
