I completely agree with everything you said. What makes me happy discussing this stuff with you is that you come at the topic from a different perspective than my own which helps to illuminate it.
Moving away from church and into the realms of new (or as yet) Christians I think your point about loving as we have loved etc is a good point. I cannot think of a verse in the Bible that tells us why we should be saved, rather it is taken as a given. You should have a relationship with God because you should. I think the reasons you gave are the closest to a eral reason. God has given should you too should give.
So here’s my thinking on what Christianity is (this comes straight from the script I was working on):
“So let’s refine the reason for becoming a Christian that puts God front and centre: it’s the belief that there is a God who created all things including us. He gave us free will and because of Satan’s influences we’ve used that free will to do our own thing and shun a relationship with God.
Think of life like a sport’s team, let’s say soccer. Everyone has their position and they work together to win. Then you have defenders deciding they want to be strikers and get the glory and midfielders who don’t trust the defenders and move up and down. Ultimately everyone is getting what they want, but they’re no longer working together to win the prize.
So, God came to Earth in the form of a man named Jesus and it was through His death and resurrection that we are reunited with God and fitted back into His excellent plan.”
See I think the point of Christianity comes back to purpose. God wanted something done so He created us with specific skills and talents to do that job. We’re only going to find true happiness and purpose in life when we get back into the machine, when we let go of our ego and accept we are a cog in a machine then we find purpose.
I disagree (slightly) with what you said about God having a plan to change the world, I think He knows it’s broken hence the New Heaven and New Earth. I think God has a good plan for them and wants us to get as many people into the Kingdom as possible. It’s not God’s intention that anyone should miss out, but by our own choice we deny the invitation. When we become Christians we accept entry into the Kingdom and God expects us to live like we will then. After all, if we can’t do it now (or at least try) how are we going to do it then?
A last thought: Verses like Romans 8:28 and Jeremiah 29:11 talk about God having a plan for us, but nowhere else does the Bible talk about plans in terms of something on the is Earth that is a blessing. Jesus constantly talks about being a servant and that the last will be first. I think that’s God’s plan, serve now in the Shadowlands and enjoy the Kingdom when the work is finished.
