My wife consistently deals with people pressuring her to believe a great lie. It is the lie that you can have more faith in today's prophet than you can in yesterday's prophet, and that we cannot stand by both of them together, and thus must discard the early prophets of this dispensation that we can fully be devoted to the prophets of this day.
Is Christ divided?
What do the scriptures say of those who are of Paul, and of Apollos, and of Cephas?
D&C 76: 99 For these [the telestial] are they who are of Paul, and of Apollos, and of Cephas.
100 These are they who say they are some of one and some of another—some of Christ and some of John, and some of Moses, and some of Elias, and some of Esaias, and some of Isaiah, and some of Enoch;
101 But received not the gospel, neither the testimony of Jesus, neither the prophets, neither the everlasting covenant.
And that is, at least in part, because you cannot receive only part of the gospel and only some of the prophets and be a true latter day saint.
You can shoot your faith in the foot by rejecting today's prophets and apostles, and not recognizing them for what they are. And you can shoot your faith in the foot by rejecting yesterday's prophets and apostles.
And if you shoot your faith in the right foot so that you are are forced to place your full weight on your left you may feel confident in that choice for a moment. Standing there pretentiously poised you may feel strong. But once you need to start walking forward along the strait and narrow path, you will find that it climbs upward in places, and that you have slowed your pace to a hop and thoroughly crippled your ability to traverse its steeper moments.
You cannot believe that the man at the head of the church today holds all the keys of the kingdom and that the man at the head of the church yesterday did not. You cannot sustain todays prophets and apostles as prophets, seers, and revelators more sincerely than you can sustain yesterdays prophets and apostles. Todays leaders obtained their keys from yesterdays leaders. They are one in Christ.
God will not bestow an extra measure of his spirit spirit for embracing one prophet if you do so while poking another in the eye.
Did they not testify by the same spirit of God? And as they spoke by the same spirit of God, can we reject either without offending that same spirit?
Other churches pick and choose among the words of the prophets, believing this from one and that from another. But with with us it is not so. We only have a living prophet because we previously had living prophets. We only have living apostles because we previously had living apostles. There are no revolutions, no coups, no toppling of former governments in God's true church. There is God. And he is the head. And when we reject the words of one of his prophets ancient of modern, we do so at our peril.
