Active righteousness is man's useless attempt to earn his own salvation by obeying the Law and doing good works (like the Pharisee in the parable).

主动的义是指人们无谓的尝试，企图通过遵守律法和善工来赚取救恩（像比喻中的法利赛人一样）。

But there are many still flout the law students for many reasons, but I think there are a lot of people believe in "useless study."

可是有很多同学还是明知故犯，原因有很多，但我想，当中有很多人信奉“读书无用论”。

But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless.

要远避无知的辩论、和家谱的空谈、以及分争、并因律法而起的争竞。因为这都是虚妄无益的。
