Water doesn’t go under the bridge twice. (Author unknown)

We don’t know what the originator of this expression meant, but we can learn at least two things from it. 1) Water will flow under the bridge in only one direction. To change its direction would require significant labor and most likely would not be worth it. 2) Perhaps, it’s another way of saying, “Opportunity knocks only once.” Take advantage of it while you can.

Therefore, whenever we have the opportunity, we should do good to everyone. (Galatians 6:10)

Make the most of every opportunity in these evil days. (Ephesians 5:16)
