Romans 11:20-22 Revised Standard Version (RSV)
20 That is true. They were broken off because of their unbelief, but you stand fast only through faith. So do not become proud, but stand in awe. 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.
