'Believing' 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?

So then those who are people of faith [whether Jew or Gentile] are blessed and favored by God [and declared free of the guilt of sin and its penalty, and placed in right standing with Him] along with Abraham, the believer.
