We are nothing!

If we be not in good earnest in religion, and our wills and inclinations be not strongly exercised, we are nothing. The things of religion are so great, that there can be no suitableness in the exercises of our hearts, to their nature and importance, unless they be lively and powerful. In nothing is vigour in the actings of our inclinations so requisite, as in religion; and in nothing is lukewarmness so odious. True religion is evermore a powerful thing; and the power of it appears, in the first place in the inward exercises of it in the heart, where is the principal and original seat of it. Hence true religion is called the power of godliness, in distinction from the external appearances of it, that are the form of it, 2 Tim. 3:5: "Having a form of godliness, but denying the power of it." The Spirit of God, in those that have sound and solid religion, is a spirit of powerful holy affection; and therefore, God is said "to have given the Spirit of power, and of love, and of a sound mind," 2 Tim. 1:7. And such, when they receive the Spirit of God, in his sanctifying and saving influences, are said to be "baptized with the Holy Ghost, and with fire;" by reason of the power and fervour of those exercises the Spirit of God excites in their hearts, whereby their hearts, when grace is in exercise, may be said to "burn within them;" as is said of the disciples, Luke 24:32. - Jonathan Edwards, Religious Affections, emphasis mine
