Sometimes by His word He first institutes laws, and He afterwards confirms them by His work, as when He says, The good shepherd layeth down his life for his sheep. (John 10:11) For shortly after seeking our salvation He poured out His own life. But sometimes He first sets forth in Himself an example, and afterwards, as far as words can go, draws therefrom rules of life, as He does here, shewing forth by His work these three things above the rest, the love of God, honour to parents, but the preferring God also to our parents. For when He was blamed by His parents, He counts all other things of less moment than those which belong to God; again, He gives His obedience also to His parents.
