Generally speaking, there tend to be four (4) distinct phases of belief. It is through these phases that we each acquire our most significant belief systems in life.
1. It is too absurd to be true. It's impossible to believe. Doesn't make sense.
2. I'm investigating and considering the facts, but am still puzzled --- and not convinced.
3. Personal experience occurs; a personal encounter with the truth causes me to accept the facts as truth. I'm no longer puzzled or confused about the matter.
4. Because of my conviction, I now commit myself to the truth and begin to behave differently as a result of what I now believe.
