Salvation means “to be saved from both physical and spiritual death. All people will be saved from physical death by the grace of God, through the death and resurrection of Jesus Christ. Each individual can also be saved from spiritual death as well by the grace of God, through faith in Jesus Christ. This faith is manifested in a life of obedience to the laws and ordinances of the gospel and service to Christ” (Guide to the Scriptures, “Salvation”).
Through the Atonement of Jesus Christ, the plan of salvation is freely available to everyone. This does not mean that all men and women will receive the same reward. As Alma testified, “Whosoever will come may come and partake of the waters of life freely.” But he added this warning: “Whosoever will not come the same is not compelled to come; but in the last day it shall be restored unto him according to his deeds” (Alma 42:27). Salvation is free in the sense that it is provided by the grace of God through the Atonement of Christ for all who will receive it. It is not free in the sense that it is given to all regardless of what they believe or how they choose to live their lives.
