Sounds good, but IME, misses some key points.
1. Being a disciple isn't "easy". In my world we have a scripture that states:
18 For behold he judgeth, and his judgment is just; and the infant perisheth not that dieth in his infancy; but men drink
damnation to their own souls except they humble themselves and
become as little children, and believe that
salvation was, and is, and is to come, in and through the
atoning blood of Christ, the Lord Omnipotent.
19 For the
natural man is an
enemy to God, and has been from the
fall of Adam, and will be, forever and ever, unless he
yields to the enticings of the
Holy Spirit, and
putteth off the
natural man and becometh a
saint through the atonement of Christ the Lord, and becometh as a
child,
submissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.
That process of putting off the natural man is day-to-day slog that goes on for all of mortality and will continue into he next life. Our goal is to aquire the "stature of Christ" (as per Ephesians).
Laws are necessary and the universe is governed by them. Christ taught this in the sermon on the mount and he fullfilled the old law (the law of Moses) and instituted a higher one (not only don't committ adultery.....don't even look at a woman to lust after her.....because you already have committed it).
The letter of the law is, as you say, a legalistic approach.
But following the Spirit of the Law is still following the Law.
He is eternal and he is God because of those laws. And he is bound by them. He would love to save the goats in the parable in Matthew, but eternal justice demands that not happen.
