The complexity of the universe from the microscopic to the telescopic speaks of thoughtful design.  Pure randomness is a mathematical impossibility, according to many scientists.  The Bible affirms God as creator of the heavens and the earth.  Jews believe this Creator has chosen to reveal Himself to humans.  Christians further believe that we know God because of His revelation in Jesus of Nazareth.  He came to reveal His Father, and said “if you have seen me you have seen the Father” (John 14:8-10).  The claims of Jesus are validated by His resurrection from the dead.  A clear vision of Jesus strips away false images of God and reveals a loving Creator.  We know our Abba because Jesus came.
