For if the inheritance [of never ending life] can be obtained by [obeying the requirements of] the law of Moses, it would not come from the promise [of God]; but God provided [this inheritance] for Abraham according to [His] promise.

What then is [the benefit of] the law of Moses? It was introduced [as part of God's revelation] in order to define what sin was, until the seed [i.e., Jesus] would come, to whom the promise [of never ending life] was made. The law of Moses was ordained through [the medium of] angels and [delivered] through the hand of an intermediary [i.e., Moses].

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.

But the Scriptures indicate that everything [i.e., everyone] is under the control of sin, so that the promise [of never ending life] could be available [only] to those who have faith in Jesus Christ.

If he engages in things to satisfy his own sinful desires, he will be [spiritually] destroyed for such conduct, but the one who engages in things to please the Holy Spirit will receive never ending life [as a result].

And we should not become tired of doing good things, for eventually we will receive [never ending life] if we do not give up.
