The criticism of works is a misinterpretation that is out of context with Pauls letters to gentiles that did not understand the Jewish context and background of Christ that taught of the importance of the works of faith and covenant. This is because the gentiles were dominated by Hellenistic philosophy that believed in the scales of Mott. The Hellenistic gentiles believed that sometime after death a soul would arrive at the golden gates of heaven where they would be met by Mott who had a scale in his possession. All of the good deeds of a soul were placed on the right side of the scale and all their evil deeds were placed on the left side of the scale. If the scale tipped to the right Mott admitted the soul into heaven. If the scale tipped to the left the soul was sent to hell.
During the time of Paul the Hellenistic gentiles developed the idea that if they stocked pilled enough good deeds they were justified in some fun evil deeds. Sort of like if someone was loyal to their spouse all year that it was okay to have a fun night once of year of wild adultery. Paul taught that such concepts concerning good deeds would not help one bit as a justification before G-d. Paul never taught that the works and deeds of covenant (in other words loyalty to covenants) were not necessary in order to have the gift of faith.
Jesus clearly taught that obedience to commandments was necessary before a person could have any claim to having been forgiven or to have received grace from G-d. The NT is very clear that anyone that says they love G-d and are not obedient to the commandments is not is not a disciple of Christ but is not an honest person to be believed. I recommend you take the words of Jesus to heart and turn away from teachers that deceive the sheep in any way from being obedient to their covenants.

The Old Covenant,
through the old mediator Moses,
conditioned on law keeping (If you obey me, I will be our God, and you will be my people.)
has been abolished (Eph 2:15) because it is
inferior, of lesser promises, faulty, obsolete (Heb 8:6-13),
and replaced with
the New Covenant,
through the new mediator Jesus Christ,
conditioned on faith in Jesus Christ, and is
superior, of greater promises, perfect and everlasting (Heb 8:6-13).
