Psalm 19:6

Verse 6. There is nothing hid from the heat thereof. This is literally the case. The earth receives its heat from the sun, and by conduction, a part of it enters the crust of our globe. By convection, another portion is carried to the atmosphere, which it warms. Another portion is radiated into space, according to laws yet imperfectly understood, but which are evidently connected with the colour, chemical composition, and mechanical structure of parts of the earth's surface. At the same time the ordinary state of the air, consisting of gases and vapour, modifies the heat rays and prevents scorching. Thus, the solar heat is equalised by the air. Nothing on earth or in air is hid from the heat of the sun... Even the colour of some bodies is changed by heat... Heat also is in bodies in a state which is not sensible, and is therefore called latent heat, or heat of fluidity, because it is regarded as the cause of fluidity in ponderable substances. It can fuse every substance it does not decompose below the melting point, as in the case of wood. Every gas may be regarded as consisting of heat, and some basis of ponderable matter, whose cohesion it overcomes, imparting a tendency to great expansion, when no external obstacle prevents, and this expansive tendency is their elasticity or tension. Certain gases have been liquified under great pressure, and extreme cold. Heat, also, at certain temperatures, causes the elasticity of vapours to overcome the atmospheric pressure which can no longer restrain them. An example of this is the boiling point of water; and, indeed, in every case the true instance is the boiling point. Philosophers are agreed that the affinity of heat for any ponderable substance is superior to all other forces acting upon it. No ponderable matters can combine without disengagement of heat... And the same occurs from every mechanical pressure and condensation of a body. In all these cases, and many more, there are like evidences of the presence and influence of heat; but the facts now advanced are sufficient to show us the force of the expression, that in terrestrial things nothing is hid from, or can by any possibility escape the agency of heat. Edwin Sidney, A.M., in "Conversations on the Bible and Science," 1866.

Verse 6. (last clause). There is nothing hid from the heat, nothing from the light of Christ. It is not solely on the mountain top that he shines, as in the day before he was fully risen, when his rays, although unseen by the rest of the world, formed a glory round the heads of his prophets, who saw him while to the chief part of mankind he was still lying below the horizon. Now, however, that he is risen, he pours his light through the valley, as well as over the mountain; nor is there any one, at least in these countries, who does not catch some gleams of that light, except those who burrow and hide themselves in the dark caverns of sin. But it is not light alone that Christ sheds from his heavenly tabernacle. As nothing is hid from his light, neither is anything hid from his heat. He not only enlightens the understanding, so that it shall see and know the truth; he also softens and melts, and warms the heart, so that it shall love the truth, and calls forth fruit from it, and ripens the fruit he has called forth; and that too on the lowliest plant which creeps along the ground, as well as the loftiest tree...

Though while he was on earth, he had fullest power of bestowing every earthly gift, yet, in order that he should be able to bestow heavenly gifts with the same all healing power, it was necessary that he should go up into heaven. When he had done so, when he had ascended into his tabernacle in the heavens, then, he promises his disciples, he would send down the Holy Spirit of God, who should bring them heavenly gifts, yea, who should enter into their hearts, and make them bring forth all the fruits of the Spirit in abundance; should make them abound in love, in peace, in longsuffering, in gentleness, in goodness, in faith, in meekness, in temperance. These are the bright heavenly rays, which, as it were, make up the pure light of Christ; and from this heat nothing is hid. Even the hardest heart may be melted by it; even the foulest may be purified. Julias Charles Hare, M.A., 1841.
