Listen to an excellent sermon from Tim Keller here. ?The blurb on the website summarises the sermon as follows:
Many people think that if you believe in a literal second coming of Christ, then you won?t care about improving this world at all. Yet, the Bible teaches the exact opposite. It is because Christians believe in a coming age without sin and injustice that they eagerly work in this world to bring about glimpses of the world to come. This belief influences everything a Christian does?including their work. Christians must not segregate their faith from their work, but must wrestle with the challenge of glorifying God in their vocations.
