“And they also, if they bide not still in vnbeliefe, shall be graffed in: for God is able to graffe them in againe.”
1611 King James Version (KJV)
Ro 11:23 And they also, if they abide not still in unbelief. As Gentile believers will be cut off unless they "continue in the goodness of God" (Ro 11:22), so the Jews, if they abandon their unbelief, shall again be grafted in. They are not cut off by a decree of God casting them away, but by their own unbelief.
