17 If some of the branches were broken off, and you were a wild olive branch, and you were grafted in among the other branches and shared the root that produces the rich oil of the olive tree,
18 then don’t brag like you’re better than the other branches. If you do brag, be careful: it’s not you that sustains the root, but it’s the root that sustains you.
19 You will say then, "Branches were broken off so that I could be grafted in."
20 Fine. They were broken off because they weren’t faithful, but you stand only by your faithfulness. So don’t think in a proud way; instead be afraid.
21 If God didn’t spare the natural branches, he won’t spare you either.
22 So look at God’s kindness and harshness. It’s harshness toward those who fell, but it’s God’s kindness for you, provided you continue in his kindness; otherwise, you could be cut off too.
23 And even those who were cut off will be grafted back in if they don’t continue to be unfaithful, because God is able to graft them in again.
