So, what is the point of Christianity? I reject the answer that it's about 'getting to heaven'. To steal a line from N.T. Wright, the scriptures are pretty clear that God's purposes aren't about getting us into heaven, but rather getting heaven into us.
There's talk of us having the fullest possible life. There's the part of the Lord's Prayer asking for God's kingdom and will to be present on earth. In John 17, Jesus prays for everyone who will ever believe in him (v.20) and he specifically says, "I’m not asking you to take them out of the world..." (v.15).
No, our goal isn't to escape this world. It is to be part of God's restoration of this world. To prepare the way for God's justice and redemption by seeking those things in the areas of our life where we have the opportunity to make a difference.
So then, back to the question at hand. How do I know if I'm doing this correctly?
