How can a person be sure - before it is too late - that they have made the right decision about God?
How can a person be sure - before it is too late - that they have chosen the right path to seek God?
Quite easy. Look at the evidence.
The god concept is born from pure fantasy, there is not a single scrap of evidence to support the possibility of gods. But absence of evidence does not necessarily mean non-existence. Let's good at the issue another way.
For your god to have meaning there must be a spirit world, of souls, and heaven and hell etc. This then depends on the soul concept being credible.
The soul concept appears to have begun when people noticed that dead people have no breath and it was assumed that this "breath" was a person's essence or soul. The word comes from breath or air. This gave rise to the idea that dead souls were floating around in the ether and could be breathed in and cause possessions etc. Most deceases at one time were thought to be the result of such possessions.
We know all that is now nonsense but the concept had taken hold and evolved and became more sophisticated over the years. The soul was considered the very basis of -
Emotions
Personality
Thought
Reasoning
Identity
Memory
Endless clinical studies over the past century or so has found quite clearly that all those aspects of humans is entirely the result of brain function.
What then does a soul do if none of those? Nothing. The properties of a soul can be easily equated to anything that does not exist.
Very simply there is no role that a soul can now perform that has any meaningful context for us, they simply do not exist, and if souls do not exist, then there is no spirit realm in which gods would operate making such concepts equally ridiculous.
Think about it, if your soul survives after your death then what can it do? It would have no memory, it would not know what or who it was, it would not have any emotions, it would not be able to think, etc.
As simply as we can see that the soul concept is now redundent then too we can conclude that the god concept is equally redundant.
