Here is what great legal minds as well as experts in differing fields have said concerning biblical evidence and it's sufficiency:
1. William Lyon Phelps, for more than 40 years Yale's distinguished professor of English literature, author of some 20 volumes of literary studies, public orator of Yale, says: "and it may be said that the historical evidence for the resurrection is stronger than for any other miracle anywhere narrated"
2. Professor Ambrose Fleming, ..." says of the New Testament documents: "whether it is probably that such book, describing events that occurred about thirty or forty years previously, could have been accepted and cherished if the stories of abnormal events in it were false or mythical. It is impossible, because the memory of all elderly persons regarding events of thirty or forty years before is perfectly clear. "No one could now issue a biography of Queen Victoria, who died thirty-one years ago, full of anecdotes which were quite untrue. They would be contradicted at once.
3. In a book which has become a best-seller, Who Moved the Stone?, Frank Morison, a lawyer, "tells us how he had been brought up in a rationalistic environment, But when he came to study the facts with care, he had to change his mind, and he wrote his book on the other side. His first chapter is significantly called, 'The Book that Refused to Be Written,' and the rest of his volume consists of one of the shrewdest and most attractively written assessments I have ever read..."
4. The noted scholar, Professor Edwin Gordon Selwyn, says: "The fact that Christ rose from the dead on the third day in full continuity of body and soul - that fact seems as secure as historical evidence can make it."
5. Sir Edward Clarke, K. C. to the Rev. E. L. Macassey: "As a lawyer I have made a prolonged study of the evidences for the events of the first Easter Day. To me the evidence is conclusive, and over and over again in the High Court I have secured the verdict on evidence not nearly so compelling. Inference follows on evidence, and a truthful witness is always artless and disdains effect. The Gospel evidence for the resurrection is of this class, and as a lawyer I accept it unreservedly as the testimony of truthful men to facts they were able to substantiate."
6. Professor Thomas Arnold, cited by Wilbur Smith, This great scholar said: "The evidence for our LORD's life and death and resurrection may be, and often has been, shown to be satisfactory; it is good according to the common rules for distinguishing good evidence from bad.
7. Wilbur Smith writes of a great legal authority of the last century. He refers to John Singleton Copley, better known as Lord Lyndhurst (1772-1863), recognized as one of the greatest legal minds in British history, the Solicitor-General of the British government in 1819, attorney-general of Great Britain in 1824, three times High Chancellor of England, and elected in 1846, High Steward of the University of Cambridge, "I know pretty well what evidence is; and I tell you, such evidence as that for the Resurrection has never broken down yet."
8. Simon Greenleaf (1783-1853) was the famous Royall Professor of Law at Harvard University, Greenleaf produced a famous work entitled A Treatise on the Law of Evidence which "is still considered the greatest single authority on evidence in the entire literature of legal procedure." their writings show them to have been men of vigorous understandings. If then their testimony was not true, there was no possible motive for its fabrication."
