I was reading John 6 - my favorite book of the Bible, by the way - and I read a section about Jesus witnessing. I was suddenly struck with wonder at the simplicity of the Gospel. It is so straightforward and understandable. No other religion is like that. Most religions (if not all) require some action in order to be worthy, holy or enter heaven.
But not Jesus' Gospel.
There is one thing we have to do - then everything else falls into place.
