There is, in virtually every human heart, a great hunger for life. Jesus said to Nicodemus, "Unless one is born again, he cannot see the Kingdom of God," and Unless one is born of water and the Spirit, he cannot enter the Kingdom of God" (John 2:3, 5). God offers to every man a life that is so much higher than the physical life which men attempt to enjoy through all manner of means, and to which men tend to cling tenaciously, even at the end. This is the "abundant life" which Christ came to give us - the life of God's Kingdom. (John 10:10) Old Testament saints had been expecting Messiah to bring about a manifestation of the Kingdom by changing the political order and displacing all human rule and authority (Isaiah 2:1-4). This has not yet happened, but when it does, there will also come to pass a transformation of the very physical order of things on planet Earth (Isaiah 11:6-9).
Yet the Mystery of the Kingdom has occurred, and it is this: The Kingdom that will change the entire external order has entered This Age now to bring the blessings of God's Kingdom to men and women without changing the external order. The Old Age continues, yet men may already experience and enjoy some of the powers of the Age to Come, mainly a vital relationship with God as Father, through the New Birth. When the New Birth occurs, Kingdom life (life eternal and abundant) become available, although they belong, in unrestricted fullness, to the Age to Come. Eternal life, which we looked at in the context of Matthew 19:16 is the same eternal life into which the righteous will go at the separation of the sheep and goats (Matthew 25:46). This is all future.
Yes, much of salvation and eternal life is future. Today we have a hope (confidence) that when Christ returns, then we shall enter the Kingdom. We look forward to a day when we shall receive "a building from God, a house not made with hands" while in our present mortal bodies, we sigh with anxiety" (2 Corinthians 5:1, 4). We all, along with the Apostle Paul, long to be "clothed upon" i.e., to put on our resurrection bodies, so "that what is mortal may be swallowed up by life" (2 Corinthians 5:4). Eternal life has to do with the total man, spirit, soul and body. When we finally inherit the Kingdom of God (1 Corinthians 15:50) our bodies will be redeemed, no longer consisting of flesh and blood. Until then, we are all dying creatures....whether slowly and painfully, of enjoying a large measure of vigour until the end. Either way, God has something better when that which is mortal (our physical bodies) shall be swallowed up in life.
The future aspect of eternal life is again taught in Revelation. The "river of the water of life...flowing from the throne of God" and "the tree of life" are mentioned in Revelation 22:1-2. The revelation goes beyond this, as glorious as the salvation of the body is, to the greater reality that in our midst shall be "the throne of God and of the Lamb.....and His servants shall worship Him.....they shall see His face" (Revelation 22:3-4). All barriers of the flesh and sin will be swept away. We shall enjoy unhindered and untroubled fellowship with God. This is life; this is life eternal; this is life of the Kingdom of God.
In the next installment of this study, we will discover that there is a "now" aspect to life of the Kingdom of God. Somehow, God has managed to deliver some of the first installments of life in the Age to Come to us here and now, while we are living in this Present Evil Age, in our mortal bodies. Jesus said, "He who believes in the Son HAS eternal life" (John 3:36) and "He who hears my word and believes Him who sent Me, HAS eternal life; he does not come into judgment, but HAS passed from death to life" (John 5:24). These words are more true and powerful to me today than ever before, as I consider my father-in-laws frail body - lungs filled with fluid from pneumonia and kidneys that are working at about 30% efficiency. He is still living in his earthly tent, which is just a shadow of its former self when it could carry 2 bags of cement at a time.....but he is preparing to leave. I shared these Scriptures with him today, along with others which reminded us both of his simple faith in Jesus as Savior and Lord, exercised about 27 years ago. Because of that he can leave this life for that life, with confidence. Can you?
