Galatians 3:3-5

3 Are ye so foolish? having begun by the Spirit, are ye now made perfect by the flesh?

4 Have ye suffered so many things in vain? if [it be] yet in vain.

5 He therefore that gives unto you the Spirit and does works of power among you, [does he do it] by the works of the law or by the [obedient] ear of faith?
