The wickedness of being ashamed of Christ is very great. It is a proof of unbelief. It shows that we care more for the praise of men whom we can see, than that of God whom we cannot see.
It is a proof of ingratitude. It shows that we fear confessing Him before man who was not ashamed to die for us upon the cross. Wretched indeed are they who give way to this sin. Here, in this world, they are always miserable. A bad conscience robs them of peace. In the world to come they can look for no comfort. In the day of judgment they must expect to be disowned by Christ to all eternity, if they will not confess Christ for a few years upon earth.
Let us resolve never to be ashamed of Christ. Of sin and worldliness we may well be ashamed. Of Christ and His cause we have no right to be ashamed at all. Boldness in Christ’s service always brings its own reward. The boldest Christian is always the happiest person.
