John 2:21-25
John 2:21 (KJB)
But he spake of the temple of his body.
Here John clarifies the statement that Jesus was not referring to the physical temple because He knew in 37 years it would be destroyed and in three years, the Mosaic system of animal sacrifices would be null and void because Christ would become the final sacrifice for sin. (Heb 9:26 KJV) For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. The temple which Christ would build is no longer a physical temple but the temple of the body of believers. It would be a spiritual house which would be built all over the world consisting of believers from every country.
(1 Cor 3:16 KJV) Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
(Eph 2:20-21 KJV) And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; {21} In whom all the building fitly framed together groweth unto an holy temple in the Lord:
(1 Pet 2:5 KJV) Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
John 2:22 (KJB)
When therefore he was risen from the dead, his disciples remembered that he had said this unto them; and they believed the scripture, and the word which Jesus had said.
Jesus had expunged the moneychangers from the Temple and made the statement that the Pharisees did not understand. Jesus said, “destroy this temple and in three days I will raise it .” Since Jesus was at the physical temple, the Jews had thought He made reference to the physical temple but He was speaking about his body which would be resurrected from the dead on the third day. John states that the disciples had remembered that Jesus spoke this unto the Pharisees and then they believed the Scriptures and the word that Jesus spoke. They normally did not understand these types of sayings as they were walking with Jesus from town to town but after the final events occurred, then they remembered what was said to them as the Holy Spirit opened up the Scriptures to them. Understanding was given only to His disciples after the resurrection. The Jews were still in darkness concerning the Lord Jesus Christ because they had remained unbelievers even though He had risen from the dead.
John 2:23 (KJB)
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.
Miracles - Signs, tokens, or portent
It is obvious many had seen what Jesus did in confronting the moneychangers and the other false vendors in the Temple. When Jesus had expunged them, He was quoting Scriptures that the people would have been familiar with. This act and maybe the previous miracles Jesus did, such as at Cana, may have been in the minds of the people. The word “miracles” is the word for “signs” and Jesus was showing signs of His authority by challenging the religious establishment. It is not known if He performed any miracles at this Passover but His teachings and actions against corruption had caused many people to believe in Him as He was showing that He was not just another teacher but much more than that. There was a great number which believed in Him according to the Greek word for “many.”
John 2:24 (KJB)
But Jesus did not commit himself unto them, because he knew all men,
Commit - Have trust, confidence, or believe
As with many that believed in Him, it was not done because they were truly saved but they believed in Him based upon the miracles and signs that He did. This is why Jesus did not commit Himself to them because He knew that the belief of the great number who claimed belief was just superficial. Those whom the Lord Jesus Christ commits Himself to are those that have become truly saved through Him. This verse states that He knew the condition of these people who claimed to believe and He knew it was not a born-again based belief but based on visible signs.
John 2:25 (KJB)
And needed not that any should testify of man: for he knew what was in man.
Jesus did not need anyone to testify about the beliefs these people had or to the general spiritual condition of them. Jesus knew that their beliefs were based on what they saw and not on true salvation. Jesus, being God, would know the hearts of these people because He is omniscient. (Heb 4:12-13 KJV) For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. {13} Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do. As Hebrews 4:12-13 teaches, everything is opened unto the eyes of the Lord and nothing is hidden. (Job 22:13 KJV) And thou sayest, How doth God know? can he judge through the dark cloud? Not even darkness can keep anything hidden from the Lord.
