John 5:20 - Matthew Poole's English Annotations on the Holy Bible

For the Father loveth the Son; both as his Son by eternal generation, Matthew 3:17, and also as the Messiah sent by him into the world, to finish the work the Father had given him to do: and look, as a father will make his son acquainted with all that he doth; and not only so, but communicates all his power and skill to his son, so far as he can: so the Father communicates all his power to the Son, working all things in him, and by him; and he will in and by him work greater things than this, healing this poor man; he will by him raise the dead, &c. That ye may marvel: Christ knew that they would not believe, and all the effect that his miracles had upon the generality of the Jews, was but causing in them a stupefaction, amazement, and admiration, as 1 Thessalonians 11:47; whereas it was their duty, not only to marvel, but to have believed also, without which their admiration did but cause that they had no cloak for their sin.
