Chapter 5:25-32 Two Resurrections

25 Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.

The dead shall hear the voice of the Son of God - So did Jairus's daughter, the widow's son, Lazarus.
As the Father raiseth up the dead, so the Son quickeneth whom He will. It is God's prerogative to raise the dead, and give life, even His who first breathed into man the breath of life, and so made him a living soul. Genesis 2:7.

26 For as the Father hath life in Himself; so hath He given to the Son to have life in Himself;

For as the Father hath life in Himself -Is the living God, the fountain of life, and is the author of life to all living creatures;
Hath He given to the Son to have life, - Here our Lord speaks of Himself in His character of Messiah.

27 And hath given Him authority to execute judgment also, because He is the Son of man.

Because He is the son of man - truly and properly man; 

because though He was in the form of God, and equal to Him, yet became man, and was in the form of a servant.

28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear His voice,

The hour is coming - it is fixed to an hour, so very punctual is this great appointment....there will be a resurrection both of the just and unjust, of all that are in their graves; and though all that are dead are not in graves, or interred in the earth, as some are in the sea; yet, because the greater part are in graves, this phrase is chosen to express the universality of the resurrection: and this is also a proof of the resurrection of the same body; for what else are in the graves but bodies?

29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.

They that have done good shall come forth to the resurrection of life; they shall live again, to live for ever. 

They that have done evil to the resurrection of damnation; they shall live again, to be for dying.

30 I can of mine own self do nothing: as I hear, I judge: and My judgment is just; because I seek not Mine own will, but the will of the Father which hath sent Me.

I can of mine own self do nothing - Because of His intimate union with God.

31 If I bear witness of Myself, My witness is not true.

If I bear witness - If I had no proof to bring of My being the Messiah, and equal to God, common sense would direct you to reject My testimony; but the mighty power of God, by which I work My miracles, sufficiently attests that My pretensions are well founded.

32 There is another that beareth witness of Me; and I know that the witness which he witnesseth of Me is true.

There is another that beareth witness of Me - Meaning not His Father, who is another, and a distinct person, from Him, as the Spirit is another comforter; and both distinct testifiers from Him, as well as of Him.

Chapter 5:18-24 Jesus' Equality with God

5:18 Therefore the Jews sought the more to kill Him, because He not only had broken the sabbath, but said also that God was His Father, making Himself equal with God.

Making Himself equal with God - This the Jews understood from the preceding verse: nor did they take a wrong meaning out of our Lord's words; for He plainly stated that, whatever was the Father's work, His was the same; thus showing that He and the Father were One. 

They had now found out two pretenses to take away His life: one was that He had broken the Sabbath - ελυε, dissolved, as they pretended, the obligation of keeping it holy. 

The other was that He was guilty of blasphemy, in making Himself equal to God: for both which crimes, a man, according to the law, must suffer death.

5:19 Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing of Himself, but what He seeth the Father do: for what things soever He doeth, these also doeth the Son likewise.

Christ’s work runs parallel with that of the Father. The Father and the Son ever work in perfect harmony with one another.

5:20 For the Father loveth the Son, and sheweth Him all things that Himself doeth: and He will shew Him greater works than these, that ye may marvel.

Greater works than these - Two of these He immediately mentions:

 Raising the dead. 

And judging the world.

5:21 For as the Father raiseth up the dead, and quickeneth them; even so the Son quickeneth whom He will.

The Son quickeneth whom He will - He raiseth from death to life whomsoever He pleases. So he did, for he raised the ruler's daughter; the widow's son at Nain; and Lazarus, at Bethany.

5:22 For the Father judgeth no man, but hath committed all judgment unto the Son:

For the Father judgeth no man - That is, without the Son; which is another proof of Their equality: for that He does judge is certain.

5:23 That all men should honor the Son, even as they honor the Father. He that honoreth not the Son honoreth not the Father which hath sent Him.

As the universal Judge, the Lord is to be honored by all men, “even as they honor the Father.”

5:24 Verily, verily, I say unto you, He that heareth My word, and believeth on Him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

He that heareth My word - My doctrine - and believeth on Him that sent Me - He who credits My Divine mission, that I am come to give light and life to the world by My doctrine and death - hath eternal life - the seed of this life is sown in His heart the moment He believes - and shall not come into condemnation, εις κρισιν, into judgment - that which will speedily come on this unbelieving race; and that which shall overwhelm the wicked in the great day.
