When we have trusted Christ as our Savior and found the peace and love God gives us, it's hard to imagine someone spuring what we have so freely received. Yet as you well know, many do. Those who reject God have many stated reasons. But when we boil it all down, the reason they reject, whether they realize it or not, is that they choose sin over salvation. The story of Herod Antipas is an interesting case study of a rejecter. He rejected the message of John the Baptist, and later was a part of the trial of Jesus. Through it all, he rejected the truth yet hoped he could cover his bases by not being too cruel with them, or feeling really bad when he was. There are many "Herods" out there even today. People reject God, but hope that by being perceived as tolerant God won't be too hard on them if He does exist.
