Helaman 15

Samuel the Lamanites declares of the Lamamites to the people of Nephi that at the present time - 

"...the more part of them are in the path of their duty, and they do walk circumspectly before God, and they do observe to keep his commandments and his statutes and his judgments according to the law of Moses.

6 Yea, I say unto you, that the more part of them are doing this, and they are striving with unwearied diligence that they may bring the remainder of their brethren to the knowledge of the truth; therefore there are many who do add to their numbers daily.

7 And behold, ye do know of yourselves, for ye have witnessed it, that as many of them as are brought to the knowledge of the truth, and to know of the wicked and abominable traditions of their fathers, and are led to believe the holy scriptures, yea, the prophecies of the holy prophets, which are written, which leadeth them to faith on the Lord, and unto repentance, which faith and repentance bringeth a change of heart unto them—"  (Helaman 15:5–7)

And because they have remained "firm and steadfast" - 

"...wherewith they have been made free."  (Helaman 15:8)

Being free is conditioned upon these things.
