There is no such thing as grace that grants us blessings in violation of the scriptures. When we receive any blessing from God it is by obedience to that law upon which it is predicated. The only grace that counts for anything in matters of salvation is grace that transforms our works. It is by our works, by obedience to laws upon which blessings are predicated, that we receive any spiritual blessing from God. That is true not only in mortality, but in eternity, for we will be judged in by our works.
That is precisely the meaning of the scripture
D&C 130:20 There is a law, irrevocably decreed in heaven before the foundations of this world, upon which all blessings are predicated—
21 And when we obtain any blessing from God, it is by obedience to that law upon which it is predicated.
Those graces that change our works, that transform them, are plainly taught to us as part of our doctrine and clearly laid out in the scripture.
The light of Christ - where would we be without a conscience. It is a gift from God, we have no power to bestow it upon ourselves. The more we heed it, the more we can learn through it and be changed by it.
The Holy Ghost - this one is enormous - as it can vary from the beginning whisperings we hear all the way to the visions Joseph Smith received "while in the spirit". It is the primary means by which we become one with God. The more we heed it, the more we can learn through it and be changed by it.
The gifts of the spirit - We believe in the gift of tongues, prophecy, revelation, visions, healings, interpretation of tongues, and so forth. The more we heed them, the more we can learn through them and be changed by them.
The ministering of angels (D&C 13). No personal experience, but I'm noticing a pattern here, so I'm going out on a limb and saying that the more we heed it, the more we can learn through it and be changed by it.
The privilege of receiving the mysteries of the kingdom, to have the heavens opened to us, to commune with the general assembly and the church of the Firstborn, and to enjoy the communion and presence of God the Father, and Jesus the mediator of the new covenant. (D&C 107:19) Again, no claim to personal experience, but can we not realize that the more we heed these, the more we can learn from them and be changed by them.
These graces of God can transform our works, but they are also conditional upon our works. Truly, we are saved by grace after all we can do. We are saved by grace, but will be judged according to our works. And our works will only be judged to be good if they were transformed by God's grace. These very graces are so much a part of our doctrine, but we think they have nothing to do with redemption or the atonement.
But they are the very reason the atonement was brought to pass. That is why it is called a "preparatory redemption" in Alma 13.
Alma 13:3 ... therefore they having chosen good, and exercising exceedingly great faith, are called with a holy calling, yea, with that holy calling which was prepared with, and according to, a preparatory redemption for such.
That is why Joseph Smith taught
These, then, are all gifts; they come from God; they are of God; they are all the gifts of the Holy Ghost; they are what Christ ascended into heaven to impart (TPJS page 245)
These graces of God are the very reason the atonement was brought to pass.
