Romans 11:20-22 International Children’s Bible (ICB)
20 That is true. But those branches were broken off because they did not believe. And you continue to be part of the tree only because you believe. Do not be proud, but be afraid. 21 If God did not let the natural branches of that tree stay, then he will not let you stay if you don’t believe.
22 So you see that God is kind, but he can also be very strict. God punishes those who stop following him. But God is kind to you, if you continue following in his kindness. If you do not continue following him, you will be cut off from the tree.
