The prophet Joseph Smith taught 'Therefore ye are justified of faith and works, through grace.' The Book of Mormon teaches 'For we labor diligently to write to persuade our children, and also our brethren to believe in Christ, and to be reconciled to God; for we know that it is by grace we are saved after all we can do.' The Book of Mormon adds 'all that we could do was to repent of all our sins.' A Book of Mormon prophet named Lehi taught, 'There is no flesh that can dwell in the presence of God, save it be through the merits, and mercy, and grace of the Holy Messiah.'
Grace is a gift from Heavenly Father given through His Son, Jesus Christ. The word grace, as used in the scriptures, refers primarily to enabling power and spiritual healing offered through the mercy and love of Jesus Christ.
Everyone on earth experiences physical death. Through the grace of Jesus Christ, all will be resurrected and will live forever.
Because of personal choices, everyone also experiences the effects of sin. These effects are called spiritual death. No one can return to the presence of God without divine grace. Through the Atonement, we all can be forgiven of our sins; we can become clean before God. To receive this enabling power, we must obey the gospel of Jesus Christ, which includes having faith in Him, repenting of our sins, being baptized, receiving the gift of the Holy Ghost, and trying to follow the teachings of Jesus Christ for the rest of our lives.
The grace of God helps us every day. It strengthens us to do good works we could not do on our own. The Lord promised that if we humble ourselves before Him and have faith in Him, His grace will help us overcome all our personal weaknesses.
We are saved by grace, through the Atonement of Jesus Christ, after all that we can do. Because we are not perfect it is only through Jesus Christ that we can return through Heavenly Father. But he asks us to have faith, repent, be baptized, receive the gift of the Holy Ghost, and endure to the end. When we do this, which is all that we can do, then we are forgiven. Then we can return to our Heavenly Father.
