Galatians 3:2, 5

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?
