By faith the people passed through the Red Sea as on dry land; but when the Egyptians tried to do so, they were drowned. Hebrews 11:29
There are actually two miracles here. First, when Moses arrived at the Red Sea, he had to know that the Egyptians were near. The Red Sea parts, the Israelites stare at the spectacle in amazement, then bolt across the river bed. But even as they're crossing, they've got to have the nagging thought in their heads, "what if the river bed stays dry for the Egyptians too?" It didn't matter because they were scurrying across and didn't have a long time to answer a lot of "what if" questions. God provided a way out of their current situation and it would be foolish to lament what hadn't even happened yet! Of course we have the benefit of being able to read a few verses ahead, but they didn't have that luxury.
Instead, we have a book that's being written about our own lives. What are you trusting God for right now? Have you turned around to see the "what if" questions: what if the economy collapses, what if I lose my job, what if I can't find a spouse, what if, what if, what if. Living in the present enables us to take in every second with only a rare thought about any of the what if questions.
'What if' we eliminated those two words from our vocabularies and our thought patterns? Would it make a difference?
