“If you believe what you like in the Gospel, and reject what you don’t like, it is not the Gospel you believe, but yourself.” St Augustine 354-430
As usual, Augustine nails it. My wife used to ask people what they thought God was like. They usually just described themselves only bigger. She would then reply, “well, you’re just following yourself and trying to be God”. We’re always pre-disposed to do just that.
The Good News of Jesus has many implications. That He is King for instance. Or that He is Substitute for guilty sinners. Or that we must work out our salvation with fear and trembling. Or that He didn’t just die for individuals but shed His blood for the Church. Or that He has something to say about sex and marriage which is counter-cultural. Or that He requires us to change our relationship with money. Or that we are required not just to make a quick decision but to follow Him to the end.
We’re always eager to remake God in our own image. That’s why we need to be constantly challenged. If we read the Bible and never find anything that challenges us to change our lives or our views, then we can guarantee that we’re probably not following God but only ourselves.
