Thou art not yet fifty years old - Some MSS. read forty. The age of our blessed Lord has never been properly determined. Some of the primitive fathers believed that he was fifty years old when he was crucified; but their foundation, which is no other than these words of the Jews, is but a very uncertain one. Calmet thinks that our Lord was at this time about thirty-four years and ten months old, and that he was crucified about the middle of his thirty-sixth year; and asserts that the vulgar era is three years too late. On the other hand, some allow him to have been but thirty-one years old, and that his ministry had lasted but one year. Many opinions on this subject, which are scarcely worthy of being copied, may be found in Calmet.

1. Ye know well, Beloved, that we all have One Master, and are fellow disciples under Him. Nor are we your masters, because we speak to you from this higher spot; but He is the Master of all, who dwelleth in us all. He just now spake to us all in the Gospel, and said to us, what I also am saying to you; but He saith it of us, as well of us as of you. "If ye shall continue in My word," not of course in my word who am now speaking to you; but in His who spake just now out of the Gospel. "If ye shall …

Believing on Jesus, and Its Counterfeits
The Lord Jesus also told the contradicting sinners that the day would come when cavillers would be convinced. Observe how he put it: "When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself." Cavillers may have a fine time of it just now; but they will one day be convinced either to their conversion or their confusion. Let us hope that many will see the truth before they die--early enough to seek and find a Saviour. But many in our Lord's day who discovered …
