Римлянам 11:22

Behold therefore the goodness and severity of God: on them that fell, severity--in rejecting the chosen seed. but toward thee, goodness--"God's goodness" is the true reading, that is, His sovereign goodness in admitting thee to a covenant standing who before wert a "stranger to the covenants of promise" (Eph 2:12-20). if thou continue in his goodness--in believing dependence on that pure goodness which made thee what thou art.

The apostle, having reconciled that great truth of the rejection of the Jews with the promise made unto the fathers, is, in this chapter, further labouring to mollify the harshness of it, and to reconcile it to the divine goodness in general. It might be said, "Hath God then cast away his people?" The apostles therefore sets himself, in this chapter, to make a reply to this objection, and that two ways: - I. He shows at large what the mercy is that is mixed with this wrath (v. 1-32). II. He infers thence the infinite wisdom and sovereignty of God, with the adoration of which he concludes this chapter and subject (Rom 11:33-36).

11:22 if you stop trusting, you also will be cut off: Scripture consistently emphasizes that only believers who persevere to the end will be saved. However, Paul’s warning leads to debate over the theological implications of his statement. Some think that it implies that genuine believers can stop believing and therefore not be saved in the end. Others argue that we should not press the metaphor so far and that Paul is referring to people who appear to be believers but whose lack of real faith ultimately reveals itself.
