From this exposition take the following practical lessons--1. _All forms of religion have a tendency to lose their original purity and freshness._ As a stream, clear at its fountain-head, but turbid before it reaches the sea; as our planet, which physicists say was flung off at first from the sun a glowing mass of light and heat, has been cooling down ever since; so is it with religions and churches. As a rule, their history has been one of gathering accretions and of diminishing purity and power in proportion to their distance from their fountain-head. So was it with Judaism. So has it been with Christianity. Contrast Christianity as we have it in St. Paul's epistles, all aglow with fervour and love, and that of the time of Leo X., with its professed head and most of his court professed infidels, and the officials of the Church selling indulgences to sin for money! Luther lit the fire again; but Protestantism has had its illustrations of the same law. Witness the state of things in this country in the last century. In view of this fact let the Church pray for prophetic spirits who shall in each generation rekindle the dying fires; and, apart from the influence of specially-gifted men, let each Church betake itself continually to the Fountain-head of spiritual life. 2. _False religiousness is worse than none at all._ Isaiah says, not simply that such observances are of no avail with God, but that they are abominations to Him. We can see the reason. Such a religion as that which Isaiah denounced works harm to the individual and to the cause of godliness generally; to the individual, but inspiring him with a vain confidence; to the cause of godliness, by furnishing points for the shafts of ridicule, by which faith is killed in many hearts. It would be difficult to say who are the greatest promoters of infidelity--professed atheists or hypocritical religionists. 3. _It is a perilous thing to overlook the connection between impression and practice in religion._ In vers. 16 and 17, the prophet shows us what the true nexus between them is. "Your ceremonies and observances will do you no good unless you practise the morality, the judgment, mercy, and love to which they point." Our power of receiving impressions is under a directly opposite law from our power of practice. The former steadily decreases by exercise, the latter as steadily increases. This is so in religion, as well as in other things. The impression produced upon the Jews by the sacrifices would decrease as they were repeated, unless by them they were led to practical righteousness, and their whole system would in time become utterly powerless as a moral incentive; just as, if a man is for a few mornings wilfully deaf to an alarum in his bedroom, it presently loses its power even to waken him. The same law will operate with us. The preaching of the gospel is intended to produce impression, and that again to lead to practice. If the latter does not follow _at once,_ the chances are
