The Church wants to be both relevant and different; it needs to be able to speak to people where they are but also make a positive difference. The gospel needs to be inculturated: the good news of Jesus’ life, death and resurrection can make sense in any human culture. And the gospel critiques human culture: Jesus’ values are different from those in our cultures.
I think the Church should (and could) be relevant and different where it comes to Western European cultures of ‘time management’. In our culture it seems that the more important you are the more busy you are. The 24/7 global economy outsources labour so that ‘services’ can be maintained around the clock. ‘I have not had a free day in weeks’ is often a boast rather than a plea for help.
Surely Church culture should be different. We live because of God’s gracious gift rather than our own hard work. We cannot claim to give growth we just sow and harvest and praise God for the fruit. We have a creator to emulate and freedom from slavery to celebrate in the keeping of a day of rest, whether Sabbath or Sunday. I suggest Christians start making this relevant difference by taking the time to rest.
