-Eternal life is the gift Of God to us and we partake of this life right here on earth so it's the quality of the life we live and it's a continuation of the life we have been living here even after we go to be with the Lord.
This life is cultivated in intimacy with Jesus so we grow into this life here on earth.
When Jesus said in John 3:5 Jesus answered, "Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
This means that since the kingdom of God is supernatural and an eternal life so now that I have received Jesus and His Kingdom which is the true salvation now I walk and manifest this life.
John 17:3
[3]And this is eternal life: [it means] to know (to perceive, recognize, become acquainted with, and understand) You, the only true and real God, and [likewise] to know Him, Jesus [as the] Christ (the Anointed One, the Messiah), Whom You have sent.
Eternal life is to know God through Jesus by the Holy Spirit.
To Know Christ is to live in Him and His life being manifested through us because now we experience Him. It's feeling what motivates Him, His entire being, we perceive Jesus as He also perceives God the Father because He is the loving expression of God.
Knowing Jesus involves continual fellowship with Him, it's a realty we share with Jesus and God the Father. And this is what brings complete Joy in us. And all this is only by the Holy Spirit to enables us to do all things even fellowshiping with Jesus is only by the Holy Spirit.
1 John 5:11-13
[11]And this is that testimony (that evidence): God gave us eternal life, and this life is in His Son.
[12]He who possesses the Son has that life; he who does not possess the Son of God does not have that life.
[13]I write this to you who believe in (adhere to, trust in, and rely on) the name of the Son of God [in the peculiar services and blessings conferred by Him on men], so that you may know [with settled and absolute knowledge] that you [already] have life, yes, eternal life.
The above verses emphasize that eternal life is only and only in Jesus Christ not by works or religion or anything else.
