The man whose doctrine is shaky will be shaky in his whole life...those who are driven with every wind of doctrine are those who are too lazy to study doctrine. My observation over the years is that the people who have not been taught the truth negatively as well as positively always get carried away by the heresies and cults....
The Christian way is a difficult way of life. It is too glorious to be easy. The Christian is sorrowful, but not morose; serious, but not solemn; sober-minded, but not sullen; grave, but never cold or prohibitive; his joy is a holy joy; his happiness a serious happiness. The great need in the Christian life is for self-discipline. This is not something that happens to you in a meeting; you have got to do it! All moodiness is wrong for the Christian; we must snap out of it. There are no short cuts in the Christian life—no patent remedies. The ultimate test of our spirituality is the measure of our amazement at the grace of God.
If all the churches in the world became amalgamated, it would not make the slightest difference to the man in the street. He is not outside the churches because the churches are disunited, he is outside because he likes his sin, because he is a sinner, because he is ignorant of spiritual realities. He is no more interested in this problem of unity than the man in the moon!
—D. Martyn Lloyd-Jones, quoted in The Banner of Truth, Aug/Sep 1986
