Romans 11:20-22

ISV(i) 20 That’s right! They were broken off because of their unbelief, but you remain only because of faith. Do not be arrogant, but be afraid! 21 For if God did not spare the natural branches, he certainly will not spare you, either.
22 Consider, then, the kindness and severity of God: his severity toward those who fell, but God’s kindness toward you—if you continue receiving his kindness. Otherwise, you too will be cut off.
