You never know where the invitation will come. Abraham was sitting at home. Moses was out in the wilderness. Isaiah was in a worship service.  Matthew was at work. The woman caught in adultery was, well, caught in adultery and about to be stoned. I would call that a crisis, wouldn't you?  But it doesn't matter where you are or in what situation; God will find you. As the psalmist suggests:

Where can I go from your spirit? Or where can I flee from your presence? If I ascend to heaven, you are there; if I make my bed in Sheol, you are there. If Itake the wings of the morning and settle at the farthest limits of the sea, even there your hand shall lead me, and your right hand shall hold me fast.
