John Thomson (c. 1690-1753) was an early American Presbyterian minister. He was born in Ireland, educated in Scotland, licensed to preach by the Armagh Presbytery in Ireland, and ordained as a pastor in Delaware. He pastored churches in Delaware, Pennsylvania, and Virginia, and died while engaged in an itinerant ministry on the North Carolina frontier. He was an important figure in the passing of the Adopting Act in 1729, by which the Synod of Philadelphia officially adopted the Westminster Confession and Catechisms. He wrote several books, including An Explication of the Shorter Catechism (1749). You can read this commentary on the Westminster Shorter Catechism online here or order the newly published edition of the book here.
What I want to share from this book comes from his short epistle to the Christian reader at the end of the book. In that epistle, he gives several concluding exhortations. I have kept the original spelling and capitalization.
Now, Christian Readers, and dear Souls, for whose Sake I have been at Pains to make this little Collection of Christian Doctrines; whether you be Dissenters or of the establish'd Church, I will shut up this little Epistle, with an earnest Request to you all in the Bowels of Jesus Christ, that you would hearken unto and practise these following Particulars.First, Make serious Piety and Religion, both as to Knowledge and Practice, your main Study, remembering, that without Holiness no Man shall see the Lord. Heb. 12.142dly, Endeavour so to be aquatinted with the Principles of Religion as to have your Faith founded on the Word of God, not contenting yourselves with an implicit Faith on the Credit of any Men or Church on Earth; but labour to search the Scriptures daily, whether these Things be so. Acts 17.113dly, As we all profess to adhere to the same infallible Rule, viz. the Word of God, to believe the same Christian Doctrines, to submit to the same divine Law, both Moral and Gospel, to believe in the same common God and Saviour, to adhere to the same Covenant of Grace, to hope for the same eternal heavenly Inheritance; as we have the same common Friend and Enemies, the same Helps and Impediments of our Edification and Salvation, &c.Let us all cordially endeavour to be united in our Christian Affections and Charity towards one another, as well as true Love towards God; let us cordially strive to imitate, emulate, and encourage one another, in every Thing that is commendable before God, and agreeable to our own Consciences; and let us beware lest our differing judgments and Sentiments in lesser Points of Religion have more Influence upon us, to alienate our affections from one another than our Agreement in the more substantial Parts of Religion can have to unite and cement our Souls together in mutual Christian Love.4thly, Beware of sitting down contented with any Measure of Grace or Knowledge that you have attained, but still strive to grow in Grace, and in the Knowledge of our Lord and Saviour Jesus Christ.5thly, Be frequent and earnest in wrestling with God by Prayer, that he may pour out his Spirit, as a Spirit of Power, Light, Love, and a sound Mind, on this degenerate, backsliding Generation, that by the power of his Grace, accompanying the Gospel, he may heal the many dangerous, deadly Diseases of this sinful Age, such as Ignorance, Prophanity in Cursing and Swearing, Sabbath-breaking, Uncleanness, lifeless Formality in Matters of Religion, the prevailing prophane Neglect of Family Religion, and secret Devotion; that he would stir up all Ranks to endeavour to extend and diffuse their Influence for this Purpose, according to their Capacity, Station and Character, especially those in Authority, whether Parents, Masters, Ministers or Magistrates, by their Instruction, Example and Authority.O! how happy and glorious a prospect should we have if this were brought to pass! Then God's Salvation would be near us, and God, even our God would bless us: But if it should never be our Lot in this World to see such happy halcion Days; yet still it will be your Wisdom and Interest to strive to be of the few that enter in at the strait Gate, of the little Flock to whom your Father will give the Kingdom; and as the Furtherance of these Things was the main Design of this whole Performance; so it is and shall be the Prayer of one who desires to approve himself the Servant of your Souls, for Jesus's Sake.
