There is, however, one consideration which should weigh heavily in the estimation of every Christian, and that is, the vital nature of the doctrine of Christ's humanity. It lies at the very foundation of Christianity; and, for this reason, Satan has diligently sought, from the beginning, to lead people astray in reference to it. Almost all the leading errors which have found their way into the professing church disclose the satanic purpose to undermine the truth as to the Person of Christ. And even when earnest, godly men have sought to combat those errors, they have, in many cases, plunged into errors on the opposite side. Hence, therefore, the need of close adherence to the veritable words which the Holy Ghost has made use of in unfolding this profound and most sacred mystery. Indeed, I believe that, in every case, subjection to the authority of holy Scripture, and the energy of the divine life in the soul, will prove effectual safeguards against every complexion of error. It does not require high theological attainments to enable a soul to keep clear of error with respect to the doctrine of Christ. If only the word of Christ be dwelling richly, and "the Spirit of Christ" be in energy, in the soul, there will be no room for Satan to thrust in his dark and horrible suggestions. If the heart be delighting in the Christ which Scripture unfolds, it will assuredly shrink from the false Christs which Satan would introduce. If we are feeding upon God's reality, we shall unhesitatingly reject Satan's counterfeit. This is the best possible way in which to escape the entanglements of error, in every shape and character. "The sheep _hear His voice_, and ... follow Him; for they _know His voice_. And a stranger will they not follow, but will flee from him; for _they know not the voice of strangers_." (John x. 3-5.) It is not, by any means, needful to be acquainted with the voice of a stranger in order to turn away from it: all we require is to know the voice of "the good Shepherd." This will secure us against the ensnaring influence of every strange sound. While, therefore, I feel called upon to warn the reader against strange sounds in reference to the divine mystery of Christ's humanity, I do not deem it needful to discuss such sounds, but would rather seek, through grace, to arm him against them by unfolding the doctrine of Scripture on the subject.
