That is unbelief.
I lived there for a long, long time (like two decades), so I feel like I can speak with some authority. ;o)
If it's GOOD, it is of God. Jesus said so (through Mormon), and I believe Him.
Moroni, recording what his father Mormon preached, wrote:
Wherefore, all things which are good cometh of God; and that which is evil cometh of the devil; for the devil is an enemy unto God, and fighteth against him continually, and inviteth and enticeth to sin, and to do that which is evil continually.This song came on Spotify today as I was listening, and it became my prayer . . . it was my heart's cry yesterday, and today, as I took these words for my own and sent them heavenward, Jesus answered. With an outpouring of love and warmth and the familiar wonder of His presence, I heard in my mind and heart, infused with the unmistakable feel of His smile: "That's what I'm for, beloved. That's why I AM."
But behold, that which is of God inviteth and enticeth to do good continually; wherefore, every thing which inviteth and enticeth to do good, and to love God, and to serve him, is inspired of God. ~Moroni 7:12-13
