To keep the ten commandments or any command of God is a work.
Jesus said "If you love me, you will keep my commandments."
Honor your Father and Mother, one of the commandments, it may be
a spiritual thing or a work you do for your parents but doing what God
tells you is a work in itself. If you actively avoid committing a sin or do
a good work of charity you're doing a work. No one can work
themselves into Heaven, but are we going to be judged entirely on our
bad actions while our good actions count for nothing? Salvation is a free
gift that comes from God by way of grace, and we can't do anything that
makes us worthy of it. Faith is an essential part of salvation, but it's
necessary to do something in order to be saved. If not, the only ones
in Heaven will be the couch potatoes...........
