And if ye are Christ’s, then are ye Abraham’s seed, heirs according to promise.

And if you are Christ's, then you are Abraham's seed, and yours is the heritage by the right of God's undertaking given to Abraham.

And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.
