Having our wills increasingly swallowed up by the will of the Father actually means an enhanced individuality, stretched and more capable of receiving “all that [God] hath” (D&C 84:38). Besides, how could we be entrusted with His “all” until our wills are much more like His? Nor could His “all” be fully appreciated by the partially committed.
Frankly, it is our prospective selves we betray by holding back whatever the “part.” No need therefore to ask, “Lord, is it I?” (Matt. 26:22). Rather, let us inquire about our individual stumbling blocks, “Lord, is it this?”
The greatest happiness in God’s generous plan is finally reserved for those who are willing to stretch and to pay the costs of journeying to His regal realm.
It's ironic that the more we obey, the freer we are. All God wants for us is to be happy.
