In the event that we might have forgotten, if, when we say "The Gospel of Jesus Christ" we mean the gospel which Jesus preached, we are talking about The Gospel of the Kingdom! Last time we talked briefly about eternal life as being an integral part of God's Kingdom. Jesus said, "This is eternal life, that they might know You, the only true God, and Jesus Christ whom You have sent" (John 17:3). So eternal life begins by being brought into a personal knowledge of and relationship with Almighty God, through faith in His Son, Jesus the Christ.A second meaning of eternal life is the life of God's Spirit dwelling within us. This happens in the Present Age and prepares us for the Age to Come. Jesus said, "...unless one is born again, he cannot see the Kingdom of god....he cannot enter the Kingdom of God" (John 3:3, 5). This happens while we yet inhabit these bodies of flesh and blood which cannot inherit the Kingdom of God (1 Corinthians 15:50). Thus, inhabited by, filled with, led by the Spirit of god, we await the transformation of our mortal bodies into glorified spiritual bodies (Romans 8:17, 24; 1 Corinthians 15:42-44). This body is real, in the sense that we understand matter. Jesus, when His body had been thus glorified was able to walk right through a locked door, and then say, "...Handle Me and see, for a spirit does not have flesh and bones as you see I have" (Luke 24:39). A spiritual body is not spirit, but real, tangible and objective, yet completely and perfectly energized and empowered by the holy Spirit.
This spiritual body is a promised inheritance, and the Holy Spirit is the seal of that promise (2 Corinthians 5:4-5; Ephesians 1:14). While we do not yet possess this inheritance (it belongs to the Age to Come) we have a guarantee of it in this Present Age. A partial understanding of this is gained when you look at earnest money being paid as a deposit on the purchase of a house. That deposit guarantees future possession of the house, assuming other conditions of the contract are met. Thus the Holy Spirit is our guarantee that a redeemed and glorified body will be our possession at the proper time. So what can we conclude from this? The new birth is the beginning-partial but real-of the life of The Age to Come. We already have within us the life of heaven. It means we already participate in the life that belongs to God's future Kingdom; not its fullness, but nevertheless its reality. As Romans 8:23 says, the Holy Spirit has been given us as the firstfruits of the life to come in the resurrection. When Christ comes, we will receive the harvest - the fullness of life from God's Spirit!
Yes, the very best is yet to be; and yet we are not to live just waiting for the future. The future has already begun. It's like the words spoken by Jesus to the woman at the well in Samaria, "But the hour is coming, and now is..." (John 4:23). Because of the Holy Spirit it is now possible to worship God in spirit and in truth. This worship is far superior to the old manner of just form and function, but is just a glimpse of that which is yet to be revealed. Life in the Spirit (eternal life) is far superior to life lived just in the flesh. It means we can live in the present evil Age living the life of heaven, at least in part, while we await the Age to Come. This is the Gospel of the Kingdom!
