I have long defined 'religion' as man's hopeless and helpless attempt to reach God.
Christianity is God reaching down to Man, God came to earth for our salvation.
All to many Christians turn Christianity into religion.
I also realized many years ago while meditating on God's infinity - that if God is truly infinite - then everything I know and think about God is one small part of the infinite God. If your part is different than mine we are neither one of us wrong, we are both inadequate.
As long as we stay within God's righteousness, that boundary between what is God and what is not God - we are not wrong. As soon as we cross that boundary we are.
