Ether 2

Having compassion for the brother of Jared, the Lord said -

"Go to and gather together thy flocks, both male and female, of every kind; and also of the seed of the earth of every kind; and thy families; and also Jared thy brother and his family; and also thy friends and their families, and the friends of Jared and their families.
42 And when thou hast done this thou shalt go at the head of them down into the valley which is northward.  And there will I meet thee, and I will go before thee into a land which is choice above all the lands of the earth."  (Book of Mormon | Ether 1:41 - 42)

Conditioned on his obedience, the Lord said "will I meet thee".  From there the promises were great.  Even to a land which is choice above all lands.  After meeting them in the valley of Nimrod
 -
"...the Lord commanded them that they should go forth into the wilderness, yea, into that quarter where there never had man been.  And it came to pass that the Lord did go before them, and did talk with them as he stood in a cloud, and gave directions whither they should travel.
6 And it came to pass that they did travel in the wilderness, and did build barges, in which they did cross many waters, being directed continually by the hand of the Lord."  (Book of Mormon | Ether 2:5 - 6)

And then, what I consider significant -

"...the Lord would not suffer that they should stop beyond the sea in the wilderness, but he would that they should come forth even unto the land of promise, which was choice above all other lands, which the Lord God had preserved for a righteous people."  (Book of Mormon | Ether 2:7)

There is great symbolism here.  First they had to be obedient.  The Lord then led them continually.  And even when they came to the greatest obstacle of the ocean, the Lord would not suffer that they stop.  As we endure to the end, we are promised a land or heaven above all.
