As a protestant reinterpretation of the atonement, and particularly of the meaning of the word "grace" has been thoroughly popularized among our membership I thought I would quickly point out that there is an enormous difference between stating "His grace is sufficient" as a guiding principle by itself, and stating the phrase with its scriptural context:
Moroni 10:32 Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ; and if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God.
This is a very different message. It says "his grace is sufficient" but with an enormous, critical "if". It says:
IF ye shall deny yourselves of all ungodliness
AND love God with all your might , mind and strength
THEN is his grace sufficient for you
THAT by his grace ye may be perfect in Christ
Now there is a perfect truth. The requirements to be perfect in the grace of Christ are not light matters. To reach them someday, we must diligently strive toward them. But they are that we deny ourselves of all ungodliness (can we look at what television, books, music, websites, and movies we watch, read, and listen to and claim we are denying ourselves of all ungodliness), and that we love God with all our might, mind, and strength. These are not light matters, but as we do them we will grow into the light of Christ, and become more worthy and sensitive to the gift of the Holy Ghost. And when we really have the Holy Ghost in our life he will reveal the Savior to us line upon line, and we will become the Sons and Daughters of God.
And why does it add that "if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God"? Because real grace isn't some contract of future expectations. Real grace is experienced. It changes us here and now. It only has power to save us because it changes us here and now, for this is the day of our probation, and it is by our works that we will be judged.
