What happens if you are following someone or something and you take your eyes off of your target for a short while? It may just be to wipe your eyes or clean your glasses or something small, but once you have lost sight of your target it can be very difficult to get it back!
God wants us to love Him with all our might so that we will not lose sight of Him. If we don’t concentrate we may well lose sight of His ways and lose track of our direction!
Once we lose direction it goes downhill a bit faster than we realise!
