Knowing where you stand with God

I have been re-reading Stephen Robinson’s little book, BELIEVING CHRIST. There is a most significant passage, concerning how one who is trying to live the Gospel may know of his/her standing with Heavenly Father:
“...there is a way we can know that our efforts are acceptable, that our covenant is recognized and valid before God. If we experience the gifts of the Spirit or the influence of the Holy Ghost, we can know that we are in the covenant relationship, for the gifts and companionship of the Holy ghost are given to none else [bold my emphasis].
“Do you feel the influence of the Holy Ghost in your life? Do you enjoy the gifts of the Spirit? Then you may know God accepts your faith, repentance, and baptism and has agreed that “[you] may always have his Spirit to be with you.(D&C 20: 77)” (p. 94)

It is extremely comforting to make the connection of experiencing the gifts or presence of the Spirit with having the witness of being presently on God’s path, of having a forgiveness/remission of sins, and that continuing on this path will result in eternal life. It is also freeing, allowing more attention and efforts to be on the needs of others.

The apostle Paul was bold to call this state of standing in the grace of God, being "saved," in the present. However, it seems to me this differs significantly from the Calvinist Protestant doctrine of being "saved" in at least these ways: 1) is is conditional, rather than irreversible; 2) it becomes available through faith, repentance, baptism and then continued repentance; and 3) it is a real, personal, spiritual witness.
