This is just it. If you are a believing member of the Church of Jesus Christ of Latter-Day Saints, and I am, then you believe:
Leaders are imperfect people called of God.
We don’t vote or campaign, and you can seek a personal confirmation from God that the leaders of the church are, in fact, prophets.
The Bible teaches us that God’s ways are not our ways and His thoughts are not our thoughts, and that’s where faith comes in: trusting that the person we might pick to lead the church or the change we might want in doctrine or policy is not better than what God is doing. I believe His will is wiser than my own and I believe He speaks to individuals.
To someone who doesn’t believe in God or that He speaks to us today, it’s a total paradigm shift. But it’s fundamental to understanding why people may join or leave a church when on paper, it may or may not make sense.
