Romans 11:21-23 21st Century King James Version (KJ21)
21 for if God spared not the natural branches, take heed lest He also spare not thee.
22 Behold therefore the goodness and severity of God: on those who fell, severity; but toward thee, goodness, if thou continue in His goodness. Otherwise, thou also shalt be cut off.
23 And they also, if they abide not still in unbelief, shall be grafted in, for God is able to graft them in again.
