Some people think that the Christian church should seek to change society. This is not, from the perspective of those who think baptistically, what I see it to be all about. When I read the Book of Revelation, I cannot have that expectation.
We look towards a New Heaven and a New Earth. To be salt and light. To be light amidst the present darkness.
The mission of the church must surely be to bring proclamation and presence of the Kingdom of God into this world, among sinners. A sign and invitation towards repentance and faith.
This invitation towards repentance and faith by all is for everyone. As is God's love. But we know that not all receive.
It's not about us setting up our Kingdom. Others have tried it. Our job is to witness to God's Kingdom. So let's keep the focus and keep the faith.
