Galatians 3:3, 26

Are you so foolish and senseless? Having begun [your new life by faith] with the Spirit, are you now being perfected and reaching spiritual maturity by the flesh [that is, by your own works and efforts to keep the Law]?

For you [who are born-again have been reborn from above—spiritually transformed, renewed, sanctified and] are all children of God [set apart for His purpose with full rights and privileges] through faith in Christ Jesus.
