As he concludes his gospel, Matthew shifts the scene one more time to a mountain in Galilee, where the Lord had appointed His disciples to meet Him.  This was probably after Jesus’ appearance to them on the shores of the lake, where He tested Peter’s love, and before the day of His ascension.  At any rate, this is one of the signal events of the forty days our Lord Jesus remained on the earth following His resurrection. 

The disciples readily worshipped Him upon meeting Him on the mountain, showing that they fully accepted and revered Him as both Lord and God, even as Thomas has proclaimed Him.  But Matthew, who it ought to be recalled was one of these eleven, reports that some of them still doubted.  This is remarkable, in view of the fact that they had seen Christ on at least three occasions by now.  Nevertheless, Matthew is honest concerning the fallibility of even the best of men.  Unbelief is a deadly viper, whose head must be struck off day after day.  This also proves a strong argument against the sophism of the skeptics that the disciples were gullible men who only thought Jesus was resurrected because of overactive imagination, or through seeing an apparition of some sort.  Each gospel author gives a tale of doubt and unbelief, which it took several weeks and several appearances for Jesus to undo.  These were common sense men, not given to superstition or easily persuaded.  Their unbelief was only conquered after such a mountain of evidence had been presented that none of them could deny that Jesus was truly risen from the dead.
