23 Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did.
24 But Jesus did not commit himself unto them, because he knew all men,
25 And needed not that any should testify of man: for he knew what was in man.
27 Then he said, I pray thee therefore, father, that thou wouldest send him to my father’s house:
28 For I have five brethren; that he may testify unto them, lest they also come into this place of torment.
29 Abraham saith unto him, They have Moses and the prophets; let them hear them.
30 And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent.
31 And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
-In reference to the notion that more people would believe in this day and age if we had miracles like in the Old Testament; this is the definitive answer to that. The word “commit” in v24 is the same Greek word as “believe” in v23– “Pisteo”. Even though these people professed to believe Jesus, He did not believe them because He knew that their hearts told a different story from their mouths. We learn from this that believing because you’ve witnessed a sign does not yield a dependable faith.
Consider the account of Lazarus and the rich man from Luke 16: The rich man is certain that the returned spirit of a dead man would be able to convince his family to repent; but Abraham is quick to correct that notion by instructing the rich man that if they won’t be persuaded by Moses and the Prophets (the written Word of God), then they won’t be persuaded by anything. So take heart if you’ve never witnessed a blockbuster miracle first-hand; the greatest miracle is that God revealed His Word to the lowly human race; and His Word is more than adequate to author our faith. “So then faith cometh by hearing, and hearing by the word of God.” (Romans 10:17)
