Now it came to pass after these things that God tested Abraham... (Gen 22,1)
Abraham received the promise of the birth of a son in the beginning, and then was tested for 25 years to see if he would be able to trust God that he would actually be born. Israel accepted the promise of coming out of Egypt into the promised land, and then was tested in the wilderness before they were to enter. Gideon was told that he would deliver the Israelites from the power of the Midianites, but then he was tested several times, was supposed to overthrow the altar of his father, and then go into battle with a small handful against incredible odds. Will they believe? Jesus was tested after his baptism and filling with the Holy Spirit when he was "immediately led into the wilderness." After triumphing in the temptations, he returned "in the power of the Spirit" to Galilee. These are but a few examples which illustrate that there is always a trial between the promise and the receiving, or if you will, between the promise and our actual elevation to a higher plane of life with God. There we abound in the things of God to a far richer degree than the preceding - let us simply call it a victory.
When a man was driven out of Eden, Eden remained guarded by angels with drawn swords. The mention of the sword is meant to reassure us that it is absolutely impossible for us ever to return there. Even if we come to God and are accepted as His own children, He does not carry us back to Eden. That path is already closed in this age. But God IS with us nonetheless - in the valley of this world, accompanying us on our journey to the new creation, the new earth and heaven, something much higher than paradise. But on earth, we will probably see our lives as far more of a kind of trial than paradise, if only because we keep choosing God's way again and again. And yet, God is in this "wilderness" with us, giving us drink so that "we shall be in want of anything" but it is true because we let ourselves be led where he goes before us. We no longer seek our own ways.
Many preachers in rich countries preach a gospel in which they promise people some kind of paradise (believe and it will be well with you, Jesus is good, come to God and he will solve your problem). Sure, many of us have experienced this too, but as a secondary effect of our pursuit of God. Have you noticed that those who come to God primarily with this motive usually don't actually experience this? For the gospel preached by the apostles was otherwise: deny yourself, take up your cross, and follow Christ into eternity - at whatever cost, despite all the adversity it will cost you.
