"The early Hebrew Christians found it very difficult openly to confess Christ; for their unbelieving countrymen treated all who did so as renegades from Israel, and apostates from Israel's God. But fidelity to the truth was necessary then, and it is equally necessary now. Every believer is bound publicly to confess Christ. He must do so for Christ's sake, for his own sake, and for the sake of his fellow men." (The Pulpit Commentary)
