To the "Gentiles" of Covenant Israel:
When we exercise faith like the brother of Jared did and become sanctified in Christ, He will unfold all his revelations to us.
If we believe the Book of Mormon, we will receive manifestations of the Spirit, and know and bear record of their truth.
Jesus will lead us to all good.
If we come unto Him, Jesus will show us the knowledge that's hid up because of unbelief.
To Israel:
If we come unto Jesus, we will see all the blessings the Father has stored up for us.
When we rend the veil of unbelief and call on the Father in Jesus' name with a broken heart and contrite spirit, we will learn great and marvelous things and know the Father remembers his covenant.
To All:
The revelations of John will be opened up to us.
Those who believe and are baptized will be saved
All the faithful at the last day (who repent and come unto the Father in the name of Jesus) will be lifted up to that kingdom that's been prepared and waiting for us from before the beginning of time.
It seems to me that these two chapters prefigure the eventual uniting of Gentiles and more visible remnants of Israel into one people. That's the Lord's plan, that we should receive all the blessings he holds in store for us, together.
