Exodus 24:1, Worship you far off. This verse clearly tells us that man can approach to worship YHVH only on the basis of the blood of the Passover lamb, but not on the basis of his own works of the law, since YHVH had not yet given the full Torah to the Israelites (that would occur later at Mount Sinai in Exod 24:12).
That is not to say that the works of the Torah are not essential in one’s spiritual walk. Rather, they simply are not the basis of our salvation, but rather a guide to lead us in the paths of righteousness once we are saved, and to keep us on the path of righteousness until we die (Eph 2:8–10).
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
not of works, lest anyone should boast.
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Furthermore, Yeshua taught that our works will determine our level of rewards in his kingdom (Matt 5:19), though not our initial salvation.
Some have misunderstood Paul’s teachings to mean that since we are not saved by keeping the law, we therefore no longer need to keep the law. This is not what Paul taught! In numerous places in Paul’s writings, he upheld the validity of the Torah in the life of the redeemed believer, and even confessed that he was obedient to the law in his own life.
