Romans 11:21-23

Revised Standard Version Catholic Edition

²¹ For if God did not spare the natural branches, neither will he spare you. ²² Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness to you, provided you continue in his kindness; otherwise you too will be cut off. ²³ And even the others, if they do not persist in their unbelief, will be grafted in, for God has the power to graft them in again.
