The Scofield Bible Commentary, by Cyrus Ingerson Scofield, , at sacred-texts.com
See note, (See Scofield) - (Mat 6:33).
All terms which define the emotions or affections are comparative. Natural affection is to be, as compared with the believer's devotedness to Christ, as if it were hate.
See (Mat 12:47-50)
where Christ illustrates this principle in His own person. But in the Lord the natural affections are sanctified and lifted to the level of the divine love.
Compare (Joh 19:26); (Joh 19:27); (Eph 5:25-28).
