But now that you have come to know God [as your Father], or rather, to be known by Him [as His children], how can you turn back again to the weak, cheap, elementary teachings [of the law of Moses], to which you [seem to] desire to become enslaved?

still we know that a person is not justified [i.e., made right with God] by [perfect obedience to] the law of Moses, but rather through faith in [the person and work of] Christ. [Knowing this] we have trusted in Christ Jesus [to save us], so that we might be made right with God by trusting in Him and not by [our compliance with] the requirements of the law of Moses. Because by such law-compliance no one can be made right with God.

Is the law of Moses contrary to the promises of God? Certainly not! For if there had been a law given which could provide [never ending] life, then a person could be considered right with God by [obeying the requirements of such] a law.
