Truth is truth. The idea that Òyou believe what you want and IÕll believe whatever I wantÓ and both are equally valid is nonsense. Only when it comes to God do we accept such an absurd notion.
There is Truth concerning God. It can be known. If it IS TRUE, then it is exclusive; and, by default, all other incompatible ideas are false.
Life is short and unpredictable then comes forever. DoesnÕt it make sense to take some time to consider the Truth about eternity?
