I'm writing a sermon for Sunday about Kairos - God's eternal time. In its ancient Greek meaning, Kairos also has another meaning – the right or opportune moment. It is the ever-present breakthrough moment in God's time that must be seized in times of moral crisis to act in history as God demands. Such was the moment of Christ's birth. But there are and will be others. The German theologian Paul Tillich described Kairos in this way – " a very special time fraught with decisive consequences for good or evil when momentous things are happening, new possibilities arise, more degrees of freedom emerge, and the opportunity to seize the moment appears."
