Who is made, not after the law of a carnal commandment, but after the power of an endless life.

According to the power of life, that is, because He lives by His own power.
He had said, that there is also a change of law, and up to this point he has shown it; henceforward he enquires into the cause, that which above all gives full assurance to men's minds, [I mean] the knowing the cause thoroughly; and it leads us more to faith when we have learned also the cause, and the principle according to which [the thing] comes to pass.
