There is something in their genetic make-up, something they were created with which insures that their species will survive. They will not starve in the cold tundra of the north because there is an urge, an internal drive to move south for the winter. If the various migratory species do not obey this inner drive, they die. Similarly, I believe there is something in us humans, something instinctive, something which drives us to search for God, or for some substitute. Archaeologists have found that every known society ever discovered has some sort of religious system, and they worshipped some form of deity.
Atheists declare that it was superstition and ignorance.
The man of the enlightenment now claims to understand how the universe was created, he understands the chemical processes and no longer needs to worship God. But here we are, approaching the year 2,000 and we are still an extremely religious world. I believe God created humanity for the purpose of worshipping and serving Him. We have a free will, a right to decide whether or not we will respond to the inner urgings of the soul to worship, but the soul of man cannot find solace in an empty universe. We must worship or we will wonder through life empty, hopeless and lost.
