And if children, then heirs (namely, heirs of God and also fellow heirs with Christ) -- if indeed we suffer with him so we may also be glorified with him.

And if you belong to Christ, then you are Abraham's descendants, heirs according to the promise.

And so, since we have been justified by his grace, we become heirs with the confident expectation of eternal life."
