John Darby’s Synopsis
 The Sonship of Christ however, here below, cannot be separated from His eternal Sonship, for this lends its character to the relationship in which He stands as Son on earth in time. The passage in the text refers to verses 5 and 8, compared with 6 and 10 of chapter 5. Compare also the beginning of John 17.
 I do not think "afresh" ought to be inserted: the emphasis is on doing it for himself.
 So in Matthew 13 some with joy receive it, but there was no root.
