Ephesians Chapter 4 says nothing about Joseph Smith, Brigham Young, or any other false prophet. It doesn't say there are three gods you ought to follow or that if you join the Mormon church, you'll have the information you need to be saved.
We don't need luck --- we need
JESUS. The Bible is NOT a bunch of hooey --- Mormonism is.
Mormonism:
. We’ll sing of his goodness and mercy.
We’ll praise him by day and by night,
Rejoice in his glorious gospel,
And bask in its life-giving light.
Thus on to eternal perfection
The honest and faithful will go,
While they who reject this glad message
Shall never such happiness know.
We Thank Thee, O God, for a Prophet
