Attend church today, hear good doctrine and put that doctrine into practice.
“Doctrine has an influence upon practice, especially evangelical doctrine, spiritually understood, affectionately embraced, and powerfully and feelingly experienced; so true is what the Apostle asserts, that the Grace of God, that bringeth Salvation, the good news, the glad tidings of salvation by Christ, which is peculiar to Gospel Doctrine, hath appeared to all men, Gentiles as well as Jews, in the external ministry of the word; teaching us, to whom it comes with power and efficacy in the demonstration of the Spirit, that denying ungodliness and wordily lusts, we should live soberly, righteously, and godly in this present world, Tit. 2.11-12. Where there is not the doctrine of faith, the obedience of faith cannot be expected. Where there is not the doctrine of the Gospel, and men have not learned Christ, they live for the most part as if there was no God in the world, and give themselves up to work all sin with greediness. And on the other hand, doctrine without practice, or a mere theory and speculative knowledge of things, unless reduced to practice, is of no avail; such are the only ‘vainly puffed up in their godliness without the power of it, a name to live but are dead.’ Doctrine and practice should go together; and in order both to know and do the will of God, instruction in doctrine and practice is necessary; and the one being first taught will lead on to the other.” – John Gill, from the introduction of his Complete Body of Doctrinal and Practical Divinity
