This is the central question for each of us to consider. If there is no God or higher authority to which we are all accountable, then we can each make the rules and decide for ourselves what will be right or wrong and thus determine our own conduct and lifestyle. In such a case it would be possible for each individual to determine what is "truth" in his or her own circumstance.
However, if there is a God who made us, who is concerned about the choices we make and the path of our lives, who has provided some directions for living, wouldn't you want to know more to at least give it some consideration?
In future posts we'll look at what the Bible gives us to evaluate.
