'Belong' in the Bible

And if you belong to Christ, then you are indeed true descendants of Abraham, and are heirs in fulfilment of the promise.

Against such things as these there is no law. Now those who belong to Christ Jesus have crucified their lower nature with its passions and appetites.

So then, as we have opportunity, let us labour for the good of all, and especially of those who belong to the household of the faith.
