In this division of this work we desire to set forth in a clear, comprehensive manner the true character and principles of Christianity as seen in the teachings of the Holy Scriptures. The Bible is our only source of knowledge respecting the true nature of a Christian life. Man may presume, but the Scriptural declarations are in verity. The New Testament sets forth in such clearness the nature of a Christian heart and the conduct that naturally issues from such a heart that none need be deceived as to their spiritual standing. Christianity is in absolute and perfect accord with the Holy Scriptures. This is a fact that all must concede. No matter what may be the philosophy and theory of man, Christianity is just what the Bible plainly declares it to be. A life that is out of harmony with the sacred truth can not be a Christian life. For this reason we desire to set forth the principal teachings of the New Testament respecting practical Christianity. Chapter I. Christianity A Light. Throughout the Scriptures Christianity is spoken of as a light. The Christian era is referred to as a day. A day is when the light shineth. In speaking of the beautiful dawning of the Star of Christianity the prophet says: “And the Gentiles shall come to thy light, and kings to the brightness of thy rising.” “Arise, shine; for thy light is come.” “The sun shall be no more thy light by day; neither for brightness shall the moon give light unto thee: but the Lord shall be unto thee an everlasting light, and thy God thy glory.” Isa. 60. It is not meant to say here that Christians have no need of the light of the sun or the moon, but to teach that the light of the sun and the brightness of the moon is not to be compared to the transcendent light of Christianity. Whose heart has not been touched with a feeling of admiration as they beheld the bright dawning of the round, red sun, or the beautiful rising of a full moon? These are not to be compared with the “brightness of the rising” of the gospel day. “To them which sat in the region and shadow of death light is sprung up.” Mat. 4:16. “Through the tender mercy of our God, whereby the dayspring [sun rising—margin] from on high hath visited us, to give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.” Luke 1:78, 79. Jesus says of himself, “I am the root and the offspring of David, and the bright and morning star.” Rev. 22:16. Christ speaking to the church at Thyatira, says to those that overcome and keep his works unto the end, that he will give them the morning star. Rev. 2:28. He will give them the true light and glory of Christianity, or his own light and nature. All will do well to take heed to do his works “until the day dawn and the day star arise in their hearts.”
