Ether 4:19

And blessed is he that is found faithful unto my name at the last day, for he shall be lifted up to dwell in the kingdom prepared for him from the foundation of the world. And behold it is I that hath spoken it. Amen.

The message of conditional salvation is repeated over and over. Salvation is a gift. We are lifted into heaven; we don't climb in on our own power. But the gift is given to those who are faithful. We don't have to be perfect, just true, constant, trustworthy keepers of covenants.

3 Nephi 17:8

For I perceive that ye desire that I should show unto you what I have done unto your brethren at Jerusalem, for I see that your faith is sufficient that I should heal you.

Apparently faith is measurable. God measures our faith by our faithfulness, humility, and patience. For our faith to have power, we must be "all in". He expects is to do all we can for ourselves first and then turn to him to complete what we cannot do on our own, and then wait for him to work. It is counter to faith to rush to the Lord first while keeping a back-up plan in our hip pocket in case God does not come through to our liking.
