We scarcely deem it necessary to refer again to the--almost universally conceded--fact of man's immortal nature. By the breath of God, man was made a living soul or spirit. God's spirit is _living fire_; hence this immortal nature of man is _living fire_, an attribute of God himself, and one which can never cease to exist; can never be annihilated, but will live on, and on through all eternity. But when this immortal principle of _spirit-fire_ leaves the body, mortality ceases to live, and must decay and moulder into dust. For, speaking of this mortal body, He hath said, "dust thou art, and unto dust shalt thou return," and "the soul shall return to God who gave it." _SUN AND HEAVEN._ Now to show the intimate connexion with the _Sun_ and _Heaven_, spoken of in the Scriptures, we will here group together a few of the many passages found written therein. The prophet Jeremiah, in referring to the great and terrible day of the Lord, says "the light shall be darkened in the heavens;" and in the Gospel according to St. Mark, referring to the same, we read that "the _Sun_ shall be darkened;" and in the Revelation, that "the _Sun_ and the air were darkened." Again, Jehovah, speaking to His people, saith: "I will cover the _heaven_, and make the stars thereof dark;" and, in order that we may more fully comprehend, he added: "I will cover the _Sun_ with a cloud;" and the Psalmist tells us that "He covereth the _heaven_ with a cloud;" and thus saith the Lord through His prophet: "Be not dismayed at the signs of _heaven_; for the heathen are dismayed at them." Thus we see that the _Sun_ and _heaven_ are often spoken of in connexion with each other in regard to light. The Sun is to us the source of _all light_, and in covering the _heaven_ He covereth the Sun. But we see, as above, that He hath made this matter plain to our comprehension by His own utterance: "_Be not dismayed by the signs of heaven; for the heathen are dismayed at them._" Now you will remember that the heathen, in ancient times--and even so with them at the present day--were always dismayed and frightened at the recurrence of an eclipse of the Sun, and imagined the time of the world had come to an end. But the science of astronomy has comprehended the laws of nature, and has revealed the true causes of these seeming phenomena to the enlightenment of the world, and many years previous to their occurrence. Astronomers can foretell the day, the hour, and even the very moment when they will appear, or be visible in any part of the world, as, also, when they will disappear. But we see, however, that God himself has spoken of such eclipses as "signs in the _heaven_," and yet they are eclipses of the _Sun_.
