o love Christ in the hearts and confess him with their mouths
For us to love Christ and confess Him is an entire lifestyle. It does not mean that we make an impassioned prayer once in time, for all time, but that we live out a committed life of discipleship. We also believe we have the choice/freedom to walk away from Christ at any time.
How can I read those things and believe that works cause me to be saved?
I don’t see how anyone could. You don’t think Catholics believe this, do you?
But they do not cause me to be a born again, Spirit filled, adopted, changed, child of God.
There is one “work” that does cause this, but it is one that comes from God, and is then given back to God.
You also make an essential point here, that when we are justified, we are “changed”. We are not just “accounted righteous”, as though God doctored the books. We are infused with grace, and essentially changed in our hearts.
. Nor do they keep me a born again, Spirit filled, adopted, changed, child of God.
I agree that one cannot have these events “undone”, but doing the works that God created beforehand, that we should walk in them, does keep us in a state of grace, so that we can live out the reality of these conditions. We can lose our state of being spirit filled, and fail to live out our changed inner state, and act like we are no longer a child of God.
If my works cause me to be counted as righteous (now or in the future) then I am earning my salvation.
Not in this case, as
ergos hagios do not originate in human nature, but in grace. It is as though we are the glove, moved by God’s hand in our hearts. This is what is meant by working our our salvation with fear and trembling. We cooperate with His grace, but we are not the Source of it.
