God is, according to the scripture the beginning and end of all things; Humanly spoken things always have a beginning and an end. The Bible was written from our viewpoint and in that there always is a beginning and an end. Yet, one immediately has to realize that God himself excedes that. This can hardly be imagined by men and therefore looks impossible to us, because we don't know it and therefore we can't understand it, but that does not mean it wouldn't be true. God is without beginning and end, says the Bible, from eternity to eternity He is God (Isaiah 43:10-13). He has always been there and will always be there. Got is eternal and the cause of all that we know.
Regarding people: we have a two-sided starting point: namely, first: the beginning of man in general sense, as mankind, by the creation of the people Adam and Eve. Second: of course the beginning of ourselves as a person, not after our birth, as most will say/think, but yet before birth, namely in the womb of our mother; as body yet without form (Psalm 139:16). We as a person, however, have no ending according to the Bible. We (our soul) will exist forever1; or, eventually, in heaven, or on the new earth, in both cases with God, or in hell; for ever departed from God.
But, some shall say, if we know one thing certain is that we all die. Yes, but that is our earthly dead, the moment that we leave the tent that we live in, and our body will be broken down (2 Corinthians 5:1-5, 2 Peter 1:13-14). So, our body is pictured, in the Bible, as a tent, a temporarily living that we can leave. So, with our earthly death2 it does not stop, as many do think/believe.3 (Luke 16:22-31, Matthew 28:5-6, John 5:28, 1 Corinthians 15:21-22, Fillipians 1:23)Our world, our earth and the universe, started, according to the Bible (Genesis 1 and 2), because God created it in 6 days (I believe that). It took place about 6000 years ago. That age can be determined by genealogical registers in the Bible. That there is a lot of doubt about that nowadays, also by christians, is clear, not in the least place caused by the influence science and evolution theory. I will go into that separately (see menu left).
About the end of the world as we know it, the Bible says it will pass away; there will be a new heaven and a new earth (Matthew 5:18, 24:35, 2 Peter 3:10, Revelation 20:11, 21:1). Yet the new earth will be for ever, because Christ's government shall never end (Daniel 2:44, 7:14). It will be without decay and will also not be replaced by another kingdom. It is eternal. The only thing that changes is that the Christocracy of the (millanial) Kingdom will be handed over to full theocracy when the period of the new heaven and new earth will begin (1 Corinthians 15:24). Christ will, however, as yet was made clear by Daniel, still reign then. When God then will be 'all in all', it speaks about the trinity-God, but in essence the Kingdom will not change.
