What do I mean when I speak of a true Christian? Do I mean everybody who goes to church or chapel? Do I mean everybody who professes an orthodox creed, and bows his head at the belief? Do I mean everybody who professes to love the Gospel? No: indeed! I mean something very different. All are not Christians who are called Christians. The man I have in view is _the Christian in heart and life_. He who has been taught by the Spirit really to feel his sins,--he who really rests all his hopes on the Lord Jesus Christ, and His atonement,--he who has been born again and really lives a spiritual, holy life,--he whose religion is not a mere Sunday coat, but a mighty constraining principle governing every day of his life,--he is the man I mean, when I speak of a true Christian. What do I mean when I say the true Christian is happy? Has he no doubts and no fears? Has he no anxieties and no troubles? Has he no sorrows and no cares? Does he never feel pain, and shed no tears? Far be it from me to say anything of the kind. He has a body weak and frail like other men; he has affections and passions like every one born of woman: he lives in a changeful world. But deep down in his heart he has a mine of solid peace and substantial joy which is never exhausted. This is true happiness. Do I say that all true Christians are equally happy? No: not for a moment! There are babes in Christ's family as well as old men; there are weak members of the mystical body as well as strong ones; there are tender lambs as well as sheep. There are not only the cedars of Lebanon but the hyssop that grows on the wall. There are degrees of grace and degrees of faith. Those who have most faith and grace will have most happiness. But all, more or less, compared to the children of the world, are happy men. Do I say that real true Christians are equally happy at all times? No: not for a moment! All have their ebbs and flows of comfort: some, like the Mediterranean sea, almost insensibly; some, like the tide at Chepstow, fifty or sixty feet at a time. Their bodily health is not always the same; their earthly circumstances are not always the same; the souls of those they love fill them at seasons with special anxiety: they themselves are sometimes overtaken by a fault, and walk in darkness. They sometimes give way to inconsistencies and besetting sins, and lose their sense of pardon. But, as a general rule, the true Christian has a deep pool of peace within him, which even at the lowest is never entirely dry.[8] 8: I use the words, "as a general rule," advisedly. When a believer falls into such a horrible sin as that of David, it would be monstrous to talk of his feeling inward peace. If a man professing to be a true Christian talked to me of being happy in such a case,--before giving any evidence of the deepest, most heart-abasing repentance,--I should feel great doubts whether he ever had any grace at all.
