What SweetSue may be reminding us is that no one needs to earn his/her way to heaven because that is a gift, a blessing given us by our Heavenly Father.
She is claiming that two groups are trying to earn their way to heaven when she knows nothing about (at least) one of them.
Again, the gift is offered. It's up to us to accept.
And when we say that:
......for we know that it is by
grace that we are saved, after all we can
do.
Which the OP singles out as evidence of works based and ignoring Christ......
It is in context (written prior to the Jesus's birth):
23 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 that we are saved, after all we can
do.
24 And, notwithstanding we believe in Christ, we
keep the law of Moses, and look forward with steadfastness unto Christ, until the law shall be fulfilled.
25 For, for this end was the
law given; wherefore the law hath become
dead unto us, and we are made alive in Christ because of our faith; yet we keep the law because of the commandments.
26 And we
talk of Christ, we rejoice in Christ, we preach of Christ, we
prophesy of Christ, and we write according to our prophecies, that our
children may know to what source they may look for a
remission of their sins.
