It is the glory of His kingdom. Nothing demands a greater exercise of Omnipotence than to make a depraved human heart holy. Wherever this mighty act has been performed, the saints of God should make it known. They should freely and explicitly confess it, to the glory of His name. But professions, of themselves, amount to nothing.
Unfounded professions are common.
That there are those who really enjoy the blessing of holiness we have no doubt. Precious humble souls, they are walking in all lowliness before the Lord. There are others whose professions are not well founded. This is evident from their fruits. A good tree cannot bring forth evil fruit.
