I’ve answered some other asks before about general advice and stuff living as a gay Mormon; take a gander here, here, or here.
It took me what was more or less a spiritual club over the head to finally realize the sheer magnitude of Heavenly Father’s love for me personally. That being said, there’s a lot of power in the simple truths of the gospel. We are all children of God. As He is perfect and is our Father, it follows that He is a perfect Father, and so can’t do anything but love us. His love is not contingent on our personal righteousness, nor on our attractions. His love is eternal and perfect.
Jesus Christ is no different in that regard. He experienced not only all of our sins, but also all of our heartache, pain, torment, temptation, and misery. He knows keenly what we feel. As the scriptures say, we are engraven upon His hands and feet. He took all of that on Himself out of that love for us. And because of that, He knows perfectly how to comfort us.
Sometimes we may feel unworthy, or lost, or broken. Maybe we are. But that will not and cannot stop Heavenly Father from loving us.
I know a lot of this sounds all over the place, and everything else probably sounds like it might have been ripped from a lesson manual (I would know, being a teacher for Elders’ Quorum and Sunday School), but it really is true. The best way to know for yourself, though, is through personal prayer. I don’t mean the trite kind we often find ourselves repeating just so we can say that we’ve prayed. I mean the kind of prayer that feels like you’re having a conversation with Heavenly Father. Unload. Vent. Ask questions. But then listen. That’s when you really feel the Spirit and start getting answers, and really getting closer to Heavenly Father and feeling that infinite love.
I hope this helps your friend. c:
