David Martyn Lloyd-Jones (20 December 1899 – 1 March 1981) was a Welsh Protestant minister and medical doctor who was influential in the Reformed wing of the British evangelical movement in the 20th century. For almost 30 years, he was the minister of Westminster Chapel in London. Lloyd-Jones was strongly opposed to liberal Christianity, which had become a part of many Christian denominations; he regarded it as aberrant. He disagreed with the broad church approach and encouraged evangelical Christians (particularly Anglicans) to leave their existing denominations. He believed that true Christian fellowship was possible only amongst those who shared common convictions regarding the nature of the faith.Read about Martyn Lloyd-Jones in Wikipedia
A man who imagines that because he has a head full of knowledge that he is sufficient for these things had better start learning again. 'Who is sufficient for these things?' What are you doing? You are not simply imparting information, you are dealing with souls, you are dealing with pilgrims on the way to eternity, you are dealing with matters not only of life and death in this world, but with eternal destiny.
We all tend to go to extremes; some rely only on their own preparation and look for nothing more; others, as I say, tend to despise preparation and trust to the unction, the anointing and the inspiration of the Spirit alone. But there must be no "either
or" here; it is always "both
and. " These two things must go together.
