We are here forcibly reminded of a solemn passage in the first epistle of John, in which the apostle furnishes us with the two marks whereby we may know those that are of God.--"In this the children of God are manifest, and the children of the devil: whosoever _doeth not righteousness_ is not of God, neither he that _loveth not his brother_." (1 John iii. 10.) Here we have the two grand characteristics of the eternal life of which all true believers are possessed, namely, "righteousness" and "love"--the outward and the inward. Both must be combined. Some professing Christians are all for love, so called, and some for righteousness. Neither can exist, in a divine way, without the other. If that which is called love exist without practical righteousness, it will, in reality, be but a lax, soft, easy-going habit of mind, which will tolerate all manner of error and evil; and if that which is called righteousness exist without love, it will be a stern, proud, pharisaic, self-sufficient temper of soul, resting upon the miserable basis of personal reputation. But where the divine life is in energy, there will ever be the inward charity combined with genuine practical righteousness. The two elements are essential in the formation of true Christian character. There must be the love that will express itself in reference to the very feeblest development of that which is of God, and, at the same time, the holiness that shrinks, with intense abhorrence, from all that is of Satan. We shall now pass on to the consideration of that which the Levitical ceremonial taught with respect to "all that are in the waters." Here, again, we find the double mark. "These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat. And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you." (Ver. 9, 10.) Two things were necessary to render a fish ceremonially clean, namely, "fins and scales," which obviously set forth a certain fitness for the sphere and element in which the creature had to move.
