Charles Spurgeon Commentary Hebrews 10:23

"let us hold fast the confession of our hope that it waver not; for he is faithful that promised:" — Hebrews 10:23 (ASV)

(For he is faithful that promised; )

God gives us no cause for wavering, for he never wavers. If he were an unfaithful God, we might naturally be an unbelieving people; but he is faithful that promised. Therefore, let us hold fast the profession of our faith without wavering.

Let us holdfast the profession of our faith without wavering; (for he is faithful that promised)

As He is faithful, let us also be faithful, and hold fast, as with a death grip, the faith which has been revealed to us and worked within us by the Holy Spirit; yes, and the profession of that faith too, never being ashamed to acknowledge that we are followers of the Nazarene. And let us, while we are so faithful ourselves, endeavor to strengthen others.

Let us hold fast the profession of our faith without wavering;

Not only hold it, but hold it fast without wavering. Let us never have a question about it. God grant that we may have an unquestioning, unstaggering faith! To hold fast the profession of our faith seems enough; but to hold it fast without wavering is better still; and so we ought to do.
