12. Seeing therefore we are to make the _spirit_ and _temper_ of our prayers the _common spirit and temper_ of our lives, this may convince us, that _all orders_ of people are to labour after the _same utmost_ perfection of the Christian life. For as all Christians are to use the same holy and heavenly devotions, as they are all with the same earnestness to pray for the Spirit of God; so is it a sufficient proof, that all orders of people are, to the utmost of their power, to make their life agreeable to that one Spirit for which they all pray. *A _soldier_, or a _tradesman_, is not called to minister at the _altar_, or preach the gospel; but every soldier or tradesman is as much obliged to be devout, humble, holy, and heavenly-minded in all the parts of his _common life_, as a _clergyman_ is obliged to be zealous, faithful, and laborious in all parts of his profession. 13. *All men therefore, as men, have one and the same important business, to act up to the excellency of their rational nature, and to make _reason_ and _order_ the law of all their designs and actions. All Christians, as Christians, have one and the same calling, to live according to the excellency of the Christian spirit, and to make the sublime precepts of the gospel the rule and measure of all their tempers in common life. The one thing needful to one, is the one thing needful to all. *The _merchant_ is no longer to hoard up treasures upon earth; the _soldier_ is no longer to fight for glory; the great _scholar_ is no longer to pride himself in the depths of science; but they must all, with one spirit, _count all things but loss, for the excellency of the knowledge of Christ Jesus_. *The _fine lady_, must teach her eyes to weep, and be cloathed with humility. The _polite gentleman_ must exchange the gay thoughts of wit and fancy, for a _broken and a contrite heart_. The man of _quality_ must so far renounce the dignity of his birth, as to think himself miserable till he is _born again_. _Servants_ must consider their service as done unto God. _Masters_ must consider their servants as their brethren in Christ, that are to be treated as their fellow-members of the mystical body of Christ.
