Thank you, MHG, for providing a good example of valid opposition to the LDS Church.
I do protest to your attempt to poison the well by stating “Let you Apologists address this issue with guile from Satan.” But, you have fairly summarized our beliefs.
We believe that we are children of God. Literally. Not figuratively. And, as children do, we will one day mature; and, if we have lived a life worthy of the honor, we will receive an inheritance with Him - we will receive “all that He hath.” This is the purpose of life - to be tested to see if we are will obey God and be worthy of His highest gifts.
Those highest gifts mean being endowed with the characteristics of divinity. That means, eventually, creating spiritual children of our own who will one day be in the same condition in which we find ourselves now.
I fully recognize that this doctrine flies in the face of what is taught by mainstream Christianity. There are a number of very good reasons why it does. But disagreement is not proof; opinion is not evidence. You cite a number of Biblical verses. We simply disagree as to their interpretation. Our interpretation is informed by what we believe to be additional revelation and clarification given by God in modern times through contemporary prophets beginning with Joseph Smith.
You call this point of view heresy. Christ was also considered a heretic, so I’m not overly concerned with the label. I’m much more concerned with the pursuit of truth; and I believe this, after much study and prayer, to be a true doctrine. Though I would welcome it if you did, whether you choose to accept this view or not ultimately does not impact me. Worship as you see fit; I will do the same.
Clearly, 'giveth' refers to sexuality, thus when Luke and Paul and Matthew and Mark refer to this 'giving in marriage' they are referring not to a ceremonial ritual but to the sexual intimacy of marriage which is precisely what Jesus instructed would not be a part of the resurrection or Heaven! To teach otherwise in order to institute plural marriage is heresy. To teach that there will be 'creating of spirit children by those married who were sealed in Mormon temples on earth' is teaching heresy.
So just WHO did GOD 'literally' have intercourse with to 'create' us?
This is the purpose of life - to be tested to see if we are will obey God and be worthy of His highest gifts.
Good luck!
