What about the apostasy passages? (Hebrews 10, John 15, etc)

Paedobaptists often appeal to various “apostasy passages” as final proof that the new covenant/covenant of grace contains reprobate members who can be cut off. The important thing to note is that these passages do not teach a two-sided dual-sanction covenant of grace. Rather, paedobaptists arrive at such a view of the covenant of grace from their belief that the Mosaic covenant was the covenant of grace, and then import such a view into these passages. They believe such a view is the only way to make sense of Hebrews 10:29 and John 15:1-6, but it is important to recognize that view of the covenant of grace is brought to those texts, not derived from them.
