Let us never doubt for a moment, that the preaching of Christ crucified – the old story of His blood, righteousness, and substitution – is enough for all the spiritual necessities of all mankind.
It is not worn out. It is not obsolete. It has not lost its power. We need nothing new – nothing more broad and kind – nothing more intellectual – nothing more effectual. We need nothing but the true bread of life, distributed faithfully among starving souls. Let men sneer or ridicule as they will. Nothing else can do good in this sinful world. No other teaching can fill hungry consciences, and give them peace. We are all in a wilderness. We must feed on Christ crucified, and the atonement made by His death, or we shall die in our sins.
