We however, because of selfishness, have turned away from the Father, desiring only our own will, when we want it, no matter how much it may hurt others or the creation. This is called sin, and it is a rejection of the love of God. God in His love allows us to be as selfish as we wish, but not in His presence. When we sin, we turn our backs on God, and separate ourselves from Him. That sin also separates us from becoming part of the purpose of God for this universe, thus making our lives pointless and short. We live now in such a world — evil in part, pleasant in part, but pointless — it is a prison of our own making.

Using His Spirit, he inspired men and women around the world to reach for Him, for Meaning, for Understanding — and this has resulted in world religions — every culture has produced its own religion based on its partial understanding of God. Of all these religions, the one that understood the best about God was Judaism; so He worked with their prophets, priests, and leaders to grow that understanding, until a point was reached that would allow God to reach out to us, to come to us, and to be understood. At that point in time, God entered our world, the world of humanity, and in the power of the Holy Spirit, took our flesh and was born among us — we called Him Jesus.
