How Oft Will I Gather Israel as a Hen Gathereth Her Chickens If They Will Repent

After a massively destructive natural upheaval, Christ speaks to the surviving descendants of Lehi (who was of the tribe of Manasseh) living in the Americas.

“O ye house of Israel whom I have spared, how oft will I gather you as a hen gathereth her chickens under her wings, if ye will repent and return unto me with full purpose of heart. But if not, O house of Israel, the places of your dwellings shall become desolate until the time of the fulfilling of the covenant to your fathers.” (3 Nephi 10:6)

Questions:

-Is now the time when the covenants made regarding the restoration of Israel are being fulfilled?

-What does it entail to turn with “full purpose of heart” to Christ?
