Matthew Henry's Commentary on Mark 11:29
Commentary on Mark 11:27-33
(Read Mark 11:27-33)
Our Saviour shows how near akin his doctrine and baptism were to those of John; they had the same design and tendency, to bring in the gospel kingdom. These elders did not deserve to be taught; for it was plain that they contended not for truth, but victory: nor did he need to tell them; for the works he did, told them plainly he had authority from God; since no man could do the miracles which he did, unless God were with him.
