If you ride the tube in London, the phrase "mind the gap" soon becomes ingrained in your memory. Whenever you get on or off the train you hear a recorded voice continually reminding you of the dangerous gap that awaits unsuspecting and distracted travelers.
This little phrase has become very popular and can be found on t-shirts, has been the title of soundtracks and individual songs, and is used in various video games in the UK.
It is a good phrase to remember and to repeat as we travel in this world - we face an impossible gap between our sinful selves and a perfect Almighty God. Since Adam and Eve and the Garden of Eden, there has been a gap. We can't cross it on our own. It's only through the blood of Christ that we are able to "mind the gap" and safely begin our journey.
"When the disciples heard this, they were greatly astonished and asked, "Who then can be saved?" Jesus looked at them and said, "With man this is impossible, but with God all things are possible" (Matthew 19:25-26).
