We have far more to fear from within than from without. The hindrances to strength and success are far greater from the church itself than from the world. Unbelievers have a right to expect that those who profess to be keeping the commandments of God and the faith of Jesus, will do more than any other class to promote and honor, by their consistent lives, by their godly example and their active influence, the cause which they represent. But how often have the professed advocates of the truth proved the greatest obstacle to its advancement! The unbelief indulged, the doubts expressed, the darkness cherished, encourage the presence of evil angels, and open the way for the accomplishment of Satan's devices.
