'Doing' in the Bible

This is all I want to ask of you: did you receive the [Holy] Spirit as the result of obeying [the requirements of] the Law, or was it the result of hearing [the message of salvation and] with faith [believing it]?

So then, does He who supplies you with His [marvelous Holy] Spirit and works miracles among you, do it as a result of the works of the Law [which you perform], or because you [believe confidently in the message which you] heard with faith?

But as for me, brothers, if I am still preaching circumcision [as I had done before I met Christ; and as some accuse me of doing now, as necessary for salvation], why am I still being persecuted [by Jews]? In that case the stumbling block of the cross [to unbelieving Jews] has been abolished.

For the sinful nature has its desire which is opposed to the Spirit, and the [desire of the] Spirit opposes the sinful nature; for these [two, the sinful nature and the Spirit] are in direct opposition to each other [continually in conflict], so that you [as believers] do not [always] do whatever [good things] you want to do.

But each one must carefully scrutinize his own work [examining his actions, attitudes, and behavior], and then he can have the personal satisfaction and inner joy of doing something commendable without comparing himself to another.

Let us not grow weary or become discouraged in doing good, for at the proper time we will reap, if we do not give in.

So then, while we [as individual believers] have the opportunity, let us do good to all people [not only being helpful, but also doing that which promotes their spiritual well-being], and especially [be a blessing] to those of the household of faith (born-again believers).
