Romans 11:20-22 New Revised Standard Version Catholic Edition (NRSVCE)
20 That is true. They were broken off because of their unbelief, but you stand only through faith. So do not become proud, but stand in awe. 21 For if God did not spare the natural branches, perhaps he will not spare you.[a] 22 Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness toward you, provided you continue in his kindness; otherwise you also will be cut off.
Romans 11:20-22 New International Version (NIV)
20 Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but tremble. 21 For if God did not spare the natural branches, he will not spare you either.
22 Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.
