Matthew Poole and continuators on Hebrews 13:14

14 For here have we no continuing city, but we seek one to come.

This is an Inforcement of the fore-going Duty, as the Particle, for, cleareth, that they have no reason to be discouraged from going forth from Iudaism, and those erroneous Doctrines, and the World to him, tho it should cost them their Lives for it. For at the best, this World is not a place fit for us, nor can our state in it be desirable, since it is imperfect, fleeting, and vanishing; and we must die out of it, we may well then go forth, and die with him, and for him. And we have reason to go forth and suffer with him, since it will instantly bring us to that heavenly City, which we profess that we only live to fit our selves for, and then to enter in, and possess it, ch. 11.10, 16. and 12.22. Phil. 3.20, 21.
