In viewing my inadequacy from the perspective Jesus had when He prayed that high priestly prayer, it is easy to recognize it is the very same inadequacy that every one who believes on Him feels. As believers, as His assembly on earth, His disciples, those that are His, Jesus prayed that high priestly prayer on behalf of His own body because of our inadequacy. We believers, those who believe on the Father because of His words, are the body of Christ (see Romans12; 1 Corinthians 6, 12; Ephesians 5; Colossians 3). He prayed that high priestly prayer knowing that everyone from John who recorded it at the first, to every preacher who ever preached about it, every person who ever read it, right down to my writing a meditation, my meditation on His prayer knew that inadequacy. Seeing those first two verses (as we know them today) looking at His life with God the Father, as equal with Him, then taking the part as indeed Jesus Christ, possibly on a very familiar topic of His prayers with the Father, the work He came to do. First and foremost He glorified the Father, and then He finished the work He came to do. This follows right along with how He saw Himself as was the Father's perspective, He had glorified the Father, and now desired to glorify the Son.
Jesus continues to declare the Father's name to everyone that the Father has given Him out of this world. And like back then we believers today must likewise recognize:
Now they know that all things whatsoever thou hast given me, are of thee. For I have given unto them the words which thou gavest me, and they have received them, and have known surely that I came out from thee, and have believed that thou hast sent me.
John 17:7-8 GNV
Actually I cannot read and reread John 17 without seeing new perspective after new perspective. But no matter how this high priestly prayer is read it is always by Jesus Christ, from Jesus Christ on behalf of those disciples then and all those who would believe on the Father through their word that His Father would be glorified. He knew their inadequacy and knew what our inadequacies would be, yet He prayed for us that it wouldn't be our inadequacies, but rather the Father who would keep us and sustain us while in this world, that we would faithfully give forth the words Jesus had given them as He also received them from His Father, the entire purpose being that the Father be glorified. As one of those who later believed on the Father through their words wrote:
That we, which first trusted in Christ, should be unto the praise of his glory: In whom also ye have trusted, after that ye heard the word of truth, even the Gospel of your salvation, wherein also after that ye believed, ye were sealed with the Holy Spirit of promise,
Ephesians 1:12-13 GNV
And those who have heard and believe on the Father today from that word of truth from the Father, that "those" now includes me. Being of those Jesus Christ prayed for, praying for Himself, for His body, when He prayed that high priestly prayer I know His prayer then included me.
Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; And having an high priest over the house of God; Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works:
(Heb 10:19-24)
Jesus entered the Holy of Holies in Heaven, so that we may follow him and also enter the Holy of Holies and address God the Father directly- as he told us "Our Father who art in heaven...
The blood of Jesus is his way of life, which we must hold fast to, and show love and good works which demonstrates our love for him.
We may have been inadequate, but God expects us to be adequate, or he would not have give us his Holy Spirit to help us to live and become one with Him. "Be you therefore perfect as your Father in heaven is perfect"
We must overcome, but we have been given everything we need to be adequate and acceptable to God, if we choose to follow him, listen to his promptings and continue to choose to obey him and overcome.
