Romans 11:23

Verse 23. If they abide not in unbelief] So, we find that their rejection took place in consequence of their wilful obstinacy: and, that they may return into the fold, the door of which still stands open.

For God is able to graft them in again.] Fallen as they are and degraded, God can, in the course of his providence and mercy, restore them to all their forfeited privileges; and this will take place if they abide not in unbelief: which intimates that God has furnished them with all the power and means necessary for faith, and that they may believe on the Lord Jesus whenever they will. The veil now continues on their heart; but it is not a veil which God has spread there, but a veil occasioned by their own voluntary and obstinate unbelief: and, when they shall turn to the Lord, (Jesus,) the veil shall be taken away. See what the apostle has said, 2 Corinthians 3:6.
