Thus we may see that the Lord is merciful unto all who will, in the sincerity of their hearts, call upon his holy name. (Helaman 3:27)-
For all who will have a blessing at my hands shall abide the law which was appointed for that blessing, and the conditions thereof, as were instituted from before the foundation of the world. (D&C 132:5)-
It is significant that when we partake of the sacrament we do not witness that we take upon us the name of Jesus Christ. We witness that we are willing to do so. (See D&C 20:77.) The fact that we only witness to our willingness suggests that something else must happen before we actually take that sacred name upon us in the most important sense.
What future event or events could this covenant contemplate? The scriptures suggest two sacred possibilities, one concerning the authority of God, especially as exercised in the temples, and the other—closely related—concerning exaltation in the celestial kingdom. ("Taking upon Us the Name of Jesus Christ", Dallin H. Oaks, Apr 1985)-
And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them (Abraham 3:25)Just because we are willing does not mean we do not have to work.
[We] have plenty to do, but it is not to fill that gap. We will all be resurrected. We will all go back to God’s presence. What is left to be determined by our obedience is what kind of body we plan on being resurrected with and how comfortable we plan to be in God’s presence and how long we plan to stay there.
