Question: But what shall we do, that we may be godly?
          Answer: I shall briefly lay down some rules or helps      to godliness.
          1. Be diligent in the use of all MEANS that may promote      godliness. "Strive to enter in at the strait gate" (Luke 13:24).      What is purpose, without pursuit? When you have made your      estimate of godliness, pursue those means which are most expedient for      obtaining it.
          2. Take heed of the WORLD. It is hard for a      clod of dust—to become a star. "Love not the world" (1 John      2:15). Many would like to be godly—but the honors and profits of the world      divert them. Where the world fills both head and heart—there is no room      for Christ. He whose mind is rooted in the earth, is likely      enough to deride godliness. When our Savior was preaching against sin, "the      Pharisees, who were covetous, derided him" (Luke 16:14). The world eats the      heart out of godliness, as the ivy eats the heart out of the oak. The world      kills with her golden darts!
          3. Accustom yourselves to holy THOUGHTS.      Serious meditation represents everything in its true color. It shows the     evil of sin, and the luster of grace. By holy thoughts, the      head grows clearer and the heart better: "I thought on my ways, and     turned my feet unto your testimonies" (Psalm 119:59). If men would      step aside a little out of the noise and hurry of business, and spend only      half-an-hour every day thinking about their souls and eternity, it would      produce a wonderful alteration in them! 
          4. Watch your HEARTS. This was Christ's      watchword to his disciples: "Watch, therefore" (Matt. 24:42). The heart will      incline us to sin, before we are aware. A subtle heart needs a watchful eye.      Watch your thoughts, your affections. The heart has a thousand doors to run      out from. Oh, keep close watch on your souls! Stand continually on your      watch-towers (Hab. 2:1). When you have prayed against sin, watch      against temptation. Most wickedness in the world is committed for      lack of watchfulness. Watchfulness maintains godliness. It is the edging     which keeps piety from fraying.
          5. Make spending your TIME a matter of conscience.      "Redeeming the time" (Eph. 5:16). Many people fool away their time, some in      idle visits, others in recreations and pleasures which secretly bewitch the      heart and take it away from better things. What are our golden hours for—but      to attend to our souls? Time misspent is not time lived—but time      lost! Time is a precious commodity. A piece of wax in itself is not      worth much—but when it is affixed to the label of a will and conveys      an estate, it is of great value. Thus, time simply in itself is not so      considerable—but as salvation is to be worked out in it, and a conveyance of      heaven depends on using it well—it is of infinite concern!
          6. Think of your SHORT STAY in the world. "We      are here for only a moment, visitors and strangers in the land as our      ancestors were before us. Our days on earth are like a shadow, gone so soon      without a trace!" (1 Chron. 29:15). There is only a span between the cradle      and the grave. Solomon says there is a time to be born and a time to     die (Eccles. 3:2)—but mentions no time of living—as if that      were so short it was not worth naming! Time, when it has once gone, cannot      be recalled. "My life passes more swiftly than a runner. It flees away,      filled with tragedy. It disappears like a swift boat, like an eagle that      swoops down on its prey." Job 9:25-26. This Scripture compares time to a      flying eagle. Yet time differs from the eagle in this: the eagle flies      forward and then back again--but time has wings only to fly forward --it      never returns! "Time flies irrevocably."
     The serious thoughts of our short stay here would be a      great means of promoting godliness. What if death should come before we are      ready? What if our life should breathe out before God's Spirit has breathed      in? Whoever considers how flitting and winged his life is—will      hasten his repentance!
          7. Make this maxim your own—that godliness is the purpose      of your creation. God never sent men into the world only to eat      and drink and put on fine clothes—but that they might "Serve him in holiness      and righteousness" (Luke 1:74,75). God made the world only as a dressing      room—to dress our souls in. He sent us here on the grand errand of      godliness. Should nothing but the body (the brutish part) be looked after,      this would be basely to degenerate, yes, to invert and frustrate the very      purpose of our being!
          8. Be often among the godly. They are the      salt of the earth—and will help to season you. Their counsel     may direct you; their prayers may enliven you. Such holy      sparks may be thrown into your breasts as may kindle devotion in you. It      is good to be among the saints, to learn the trade of godliness: "He who      walks with wise men shall be wise" (Proverbs 13:20).
