The cosmological argument states that 'since there is a universe, it must have been caused by something beyond itself. It is based on the law of causality, which says that every limited thing is caused by something other than itself. The teleological argument says that first, all designs imply a designer, second, there is a great design in the universe, and third, then there must be a great designer of the Universe. Even Carl Sagan admits that the design of the universe is far beyond anything that man could devise. He is by nature moral and good.
People are good.
Whatever creates good things must be good itself. A cause can't give what it hasn't got. He must be as He is - necessary and without change. Time is not relevant or possible with Him because time is just a way to measure change. So, He is eternal.
