How could the universe come from nothing?

The universe did not come from nothing it came from God. God is a spirit being of unlimited energy and with his energy or "power" he created or converted it into matter. Isaiah 40:26 Just as E=MC2 God did the opposite and slowed down his energy to produce matter. Though God has always existed. 'This concept is difficult for mere humans who only experience and observe things that have a beginning. Those of us who know and trust God do not reject this truth just because we cannot perceive it. For instance we have not perceived the end of space, the place where gravity begins, or when living cells first developed. Scientists understand that the universe had a beginning, that beginning was God. Science can only discern the moment when God created the universe which many discribe as an instaneous expansion from a sigularity. God is the only thing along with heaven itself that has always existed, all other things have been created.
