salvation

in alma 34:15, "bring salvation to all those who shall believe on his name",
it means that if we believe in God, we shall be saved.
salvation is actually our own business,
you cannot force people to make it,
the same people cannot help you to achieve it.
we have to bring our own salvation unto ourselves.

in D&C 4:4, "bringeth salvation to his soul",
if we went go our mission, we are helping people to convert to the church,
help them to know about the gospel, hence go back to our heavenly father.
meanwhile, we are just helping ourselves to reach our own salvation.

in D&C 6:13, "no gift greater than the gift of salvation",
we can tell how valuable the salvation is,
and we are guided to how to reach it,
this is our blessing.
