William Burkitt on Matthew 10:32

Observe here, 1. That not to confess Christ, in his account, is to deny him: and to deny him, is to be ashamed of him.

2. That whosoever shall deny, disown, or be ashamed of Christ, either in his person in his gospel, or in his members, for any fear of favour of man, shall with shame be disowned, and eternally rejected by him at the dreadful judgment of the great day.

Christ may be denied three ways;

doctrinally, by an erroneous and heretical judgment; verbally, by oral expressions; vitally, by a wicked and unholy life.

But woe to that soul that denies Christ any of these ways!
