Let's assume one has concluded there is a God. Do you then live in a way where you feel lead by Him, in a spirited way, so to speak? Do you act as if daily pragmatic decisions and long term ones are lead by Him? Do you live as if your destiny is pulled forward by Him?
Or do you live as any man? God is in the background somewhere, underneath and behind everything, but the decisions you make are no different than anyone else. No special treatment is here. You are subject to the same laws of life as everyone else.
Most people I've run across who try it the first way seem to have a lot of trouble down the road. Often they never fully had their feet on the ground.
On the other hand, people who take the second route do well enough but something is lacking in their being despite their detached and Mr. Cool decisions.
There is much at stake in having an answer as far as which direction to go in. It affects your life and there are consequences. Of course on a grander scale the demarcation might not be so clear. One might go one way and than the other. Or you might just wear yourself out from trying to figure it out. It's all on the menu as we dig to answer these deep questions from within.
