John 17:1-3—Jesus spoke these things; and lifting up His eyes to heaven, He said, “Father, the hour has come; glorify Your Son, that the Son may glorify You, even as You gave Him authority over all flesh, that to all whom You have given Him, He may give eternal life. This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.”
At the conclusion of the Last Supper, Our Lord commenced what has become known as the Upper Room Discourse in John 13-17. Dr. L.S. Chafer contends that the intended audience of this discourse is different than the Sermon on the Mount or the Olivet Discourse, outlining that its content was “that form of doctrine which belongs only to the Church in the present age.”1 He maintains that it “is the seed plot of all grace teachings...and is the foundation of that which constitutes the positions, possessions, and privileges of the Christian.”2
Turning our attention particularly to the 17th chapter, known as the Great Intercessory Prayer of the Son of God, Our Lord’s prayer is directed to the Father concerned His work on the Cross, which He was about to undertake, and of His disciples, then and through the ages, that they would be kept from the evil one (vs. 15) and set apart by the Word of Truth (vs. 17).
In verse 2, Jesus proclaims that the Father has given Him “authority over all flesh (mankind)” so that He (Jesus Christ) may give them eternal life. For He is the personification of “the eternal life, which was with the Father”, as declared by John in 1 John 1:2.
In order to provide eternal life to all mankind, He would submit to the humiliation of crucifixion, sacrificing Himself for the atonement of all the sins of mankind (1 John 2:2). This fulfilled the righteous demands of the Father that resulted in “justification of life to all men” (Romans 5:18ff). This “life to all men” is what Our Lord freely gives to those who believe in Him as stated by John, along with a cautionary note:
He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him. (John 3:36)
It should be established that ‘eternal life’ is being saved from the eternal wrath of God. It is attained by faith alone in Jesus Christ in response to the gospel of salvation. The Apostle Paul gave the most concise gospel presentation in Acts 16:31: “Believe in the Lord Jesus, and you will be saved...” And the Apostle Peter boldly proclaimed this also before Annas, the high priest:
“And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.” (Acts 4:12)
Most Christians believe that eternal life simply means that we are going to heaven after death instead of the eternal punishment of Hell. However in verse 3, Jesus described eternal life not “in chronological terms [after one dies] but by a relationship.”3 This is conveyed by the Greek appositional phrase “that they may know You.” It is a grammatical usage employed frequently by John in his writings and can be translated: “This is eternal life, namely, that they may know You”4—You meaning God the Father. But unfortunately not knowing God is something which impedes the believers’ spiritual advancement. J.I. Packer astutely observed this over 40 years ago and it’s still true today:
Ignorance of God—ignorance of both of His ways and of the practice of communion with Him—lies at the root of much of the church’s weakness today.5
Dr. Merrill Tenney explains further:
For the complete fulfillment of our being, we must know God. This, said Jesus, constitutes eternal life. Not only is it endless, since the knowledge of God would require an eternity to develop fully, but qualitatively it must exist in an eternal dimension.6
Love and Fellowship
So what exactly is this relationship with the Father that defines eternal life as knowing Him? The answer to this should produce a desire in every believer to seek and experience this relationship which is fundamental for understanding the true significance of their existence.
First, this is a love relationship that we have with God the Father—the foundational component for knowing God. Our personal love for God the Father should be our appropriate response to the love He has demonstrated to us. This is supported by the Apostle Paul:
But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. (Romans 5:8; cf. 1 John 4:19)
Hence, our response should comply in the manner which Our Lord instructed:
“You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.” (Matthew 22:37; cf. Deuteronomy 6:5)
This describes the love relationship as being a mental attitude of love emanating from our heart, soul and a mind—our whole being. To accomplish this, the Apostle Paul advises that we “be transformed by the renewing of your mind” (Romans 12:2a). This is a life-long process that involves the study of God’s Word to gain the knowledge of God (2 Peter 1:3; cf. Ephesians 4:13).
Second, this relationship is described as having fellowship with all three members of the Godhead: “with the Father and His Son Jesus Christ” (1 John 1:3) and with the Holy Spirit (2 Corinthians 13:14; cf. Galatians 5:16, 25). The Greek word for ‘fellowship’ implies “an association involving close mutual relations and involvement.”7 This means that we participate or share in common all the endeavors of God.
Our fellowship with God is based upon the love relationship as John described:
We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. (1 John 4:16)
But note also, the effectiveness of our fellowship is conditioned on keeping His commandments as proof that we love Him: “If you love Me, you will keep My commandments.”(John 14:15). We are able to learn His commandments by the teaching of the Holy Spirit of truth who “abides with you and will be in you” (John 14:17)—for “He will teach you all things” (John 14:26).
Our Lord proclaimed the results of keeping His word:
Jesus answered and said to him, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our abode with him.” (John 14:23)
Making “Our abode with him” is the quintessence of fellowship with the Godhead, the Father and the Son and the Holy Spirit, indwelling the believer. This is the Divine essence of eternal life—the eternal love relationship with our Creator, as intended by the God of the universe for all mankind.
A question for those of you who believe in Jesus Christ as your Savior: Do
you strive to achieve this relationship of love and fellowship with God in your daily lives? I encourage you to do so, in order to secure the present and eternal reward of knowing God.
