That scripture you are referencing is one given in relations to making decisions. There are irrevocable laws that have governed the universe that have existed long before the world was created. Nobody gets to claim otherwise. Go into a recommend interview and tell your Bishop that you had a burning in your bosom about drinking alcohol and you won't walk out with a recommend. LDS scripture is very clear on this point.
35 That which
breaketh a law, and
abideth not by
law, but seeketh to become a law unto itself, and willeth to abide in sin, and altogether abideth in sin, cannot be sanctified by law, neither by mercy,
justice, nor
judgment. Therefore, they must remain
filthy still.
Next, you have revelation (i.e. burning in the bosom) in the New Testament:
Jesus makes the statement:
15 He saith unto them, But whom say
ye that I am?
16 And Simon Peter answered and said, Thou art the
Christ, the
Son of the
living God.
17 And Jesus answered and said unto him, Blessed art thou, Simon
Bar-jona: for flesh and blood hath not
revealed it unto thee, but my Father which is in heaven.
And when he was with his disciples:
30 And it came to pass, as he sat at meat with them, he took bread, and blessed it, and brake, and gave to them.
31 And their eyes were opened, and they knew him; and he vanished out of their sight.
32 And they said one to another, Did not our
heart burn within us, while he
talked with us by the way, and while he opened to us the scriptures?
Please explain the place of the Holy Ghost in the grand scheme of things.
As to your reference in 1 Corinthians 15, there is nothing in there about feelings. But your comment about relying on feelings is wrong if you think that is what the LDS church is about.
You might want to learn what LDS doctrine REALLY is before making any more statements about it.
Again, you are in no position, knowledgeable or not, to pass judgement on anyone else. Unless you want to post the certificate God gave you that allows you to do so.
