Galatians 3: 1 - 5
1 O foolish Galatians! Who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified?
2 Let me ask you only this: Did you receive the Spirit by works of the law, or by hearing with faith?
3 Are you so foolish? Having begun with the Spirit, are you now ending with the flesh?
4 Did you experience so many things in vain? -- if it really is in vain.
5 Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith?
