(Verse 1) - These words refers to the teaching given in the previous chapter - this prayer builds on those concepts.

It is the longest prayer recorded in the New Testament and one of the most detailed and profound.

The hour has come refers, of course, to the coming crucifixion. Glorify Your Son thus refers to that act of crucifixion. This was the hour for which He had been sent into the world. It was the hour toward which He had been moving His entire life. It is this act of obedience toward God that caps His life of active obedience that is the righteousness that is imputed ts believers at conversion. The combination of the cleansing from sin and this righteousness that was the product of obedience is what enables us to stand in the Father's presence. It was to accomplish this that Christ came. This was the authority the Father gave to Christ. The authority to establish the basis upon which His children would stand and secure both the cleansing and the righteousness that made it sure and steadfast.

There is a tie between the crucifixion of the Son and glorifying God. How did the horrible actions of these wicked men bring glory to God? There are many ways that men have put forth, but there is a particular way mentioned here. That is that He fully accomplished the work that God had given Him to do on the cross. The Son glorified the Father on the cross in that He provided the foundation of cleansing and righteousness upon which salvation stands.

This glorifies the Father in at least two ways. First, it shows to all men the true nature of God. It deononstrates in perfect balance the grace, love, and mercy of God; along with His holiness, justice, and wrath against sin. No where else do we see such perfect display of all of God's character. What attribute of God do we not see in grand and glorious view at the cross?

It also brought great glory to God in that it fully secured the salvation of all who would believe, the elect of God, His children. The death of Christ fully satisfied God's righteous indignation against sin. He completely paid the ransom debt owed the Father. He did not do this potentially. He did not make payment available, waiting to be apprehended by the sinner at later time. This hour glorified God because it brought to a close and completed the work that makes Salvation entirely a work of God.

(Verse 2) - He develops this idea here by mentioning the authority He has been given by the Father over all flesh. All flesh refers to mankind. Authority is the power to adjudicate or allocate or make judgements concerning a thing. This authority belongs to the Father but has been given to the Son. It is a delegated authority that has to do with the accomplishment of the work of the plan of God. This delegation happened, if we can speak of it this way, in eternity past. The giving of authority to the Son is and always was the focal point of the plan of God to accomplish redemption. The securing of the children of God has been placed entirely in the hand of the Son of God. It is His to exercise to the glory of God.

That He should give eternal life to as many as You have given Him stands as a sort of mission statement or charge to the Son by the Father upon the issuing of tbe mentioned authority. The reason God gave the Son such power and authority was for the express purpose of giving eternal life to as many as the Father gave to Him. That indicates, as we have said, the purpose of giving the authority to the Son. If the Son fails to give salvation to all whom the Father gave Him, then the Son has not fulfilled His task or charge. We know that Jesus completed the work God gave Him to do because He proclaimed it finished at the cross.

Note that the Word of God uses the term give and not the term offer here. It is a critical mistake bordering on blasphemy to describe the work of Christ in terms of an offer of salvation only. It is an offer, an offer to all men without distinction. However, it is far more than that. It is an actual giving of salvation to as many as the Father gave to Christ. The gift is theirs, it is not merely offered to the elect, it is, by the authority of Christ, their possession.

To as many as You have given Him certain tells us that this gift is given to some, but not to all. We can come to no other conclusion if we are to be honest with the text. The offer of the Gospel is to all men; but Christ's death actually secured (gave) salvation only to the ones whom God gave Him.

One might try and argue that God gave Him all men. However, the text simply doesn't allow for that. It is a group that is less than the whole race that is given the fruit of the work of Christ. That these are the only ones God gave Christ is the inescapable conclusion of the verse. We may not like this, but we can't avoid it if we are honest with this text. 

It is a comfort that this great gift is given to as many as God gave Christ.  He will lose none. As we noted, the giving took place in eternity past. Thus the salvation of the elect was guaranteed by the decree of God and then secured by the work of Christ. That leaves only the application of salvation by the Holy Spirit as He draws and regenerates the called child of God.

How do those facts apply to my life?:

Either salvation is secured or it is not. Either Jesus did accomplish what God sent Him to accomplish or He didn't. Either salvation is actually paid for, or it is only potential. Either it was finished at the cross or it wasn't. Either Salvation is, as the Bible proclaims, all of God or it isn't. The decision is ours - not as to whether it is so but as to whether or not we will submit to it!
