In all the prayers you must join heartily: when the Lessons are read, you will generally be able to understand them. When the Clergyman begins to preach his Sermon, try to understand what he says: if you really cannot understand his sermon, then think about some person mentioned in Scripture, as Adam, Abraham, Jacob, David, Solomon, Samuel, and many others, and consider what they did to please or displease God; or say over your hymns and texts to yourself: this will prevent your thoughts from wandering off to your business, or pleasures, or any such things. In the house of God, you must _think_ of _nothing but_ God, and how to please Him. Now let us talk of the other lesson, which we are to learn from what Jesus did. Jesus spake of His body as a temple; and St. Paul tells us, that all who love and follow Christ are so joined together in Him, that they are like stones joined together to build up a holy temple, for an habitation of God through the Spirit. As Christians baptized in the Name of the Father, Son, and Holy Ghost, we have all become stones or parts of that holy temple the Church of Christ; members or parts of His body: for the Scripture calls the Church of Christ His body. Now as long as we are obedient and faithful members of Christ's body, the Church, the Holy Spirit will bless and help us: but if we give way to our own sinful feelings, we bring bad passions into this holy temple, the Church of Christ, and "defile," or make it unclean, as the Jews defiled the temple built by hands by bringing oxen and sheep into its courts. St Paul warns us of the consequence of such sin: "If any man defile the temple of God, him will God destroy." But further, the same Apostle St. Paul teaches each one of us to look upon our own body as a temple, for the abode of the Holy Spirit. Now, as a temple is devoted to the service of God, so we must employ our bodies in serving Him, and doing His will. The temple must not be defiled; so we must try hard to keep all naughty tempers out of our hearts. Disobedience, passion, quarrelsomeness, idleness--in short, all the faults you can have--are evil things which defile the temple, and render it unfit for the abode of the Holy Spirit. If you try to resist evil, the Holy Spirit will help you to do so; but if you give way to bad passions, and allow the Devil to govern you, you will grieve the Holy Spirit of God, and at last _force_ Him to leave you to follow your own ways. To be left to follow your own evil ways is the most dreadful thing that can happen to you. Pray to God, and try to have Him always for your friend.
