And you, child, will be called a prophet of the Most High, For you will go before the face of the Lord to make ready his ways,
3. Zacharias points out the doctrine or teaching of John. It should be γνωσις σωτηριας, the science of salvation. Men are ignorant, and they must be instructed. Human sciences may be profitable in earthly matters, but cannot profit the soul. The science that teaches God must come from God. No science is of any avail to the soul that does not bring salvation with it: this is the excellence of heavenly science, and an excellence that is peculiar to itself. No science but that which comes from God can ever save a soul from the power, the guilt, and the pollution of sin.
