I believe we have now reached a situation in world history where a large number of people do not know anything about the existence of God. They may have heard about Him, but never got to know Him or experience His existence and love. So how can they possibly miss Him in their lives?
Modern lives are busy and full of distractions, concerns, worries, ambitions, goals and many other things good as well as bad on which to focus our attention.
We just do not have time for God. To search for Him, to learn about Him, and to get to know Him.
If He is not in our lives we can hardly miss Him.
Until one day when we get to meet Him face to face. And then it will be too late.
Because then we will get to really know Who God is, we would experience and witness His infinite love for His creations and yet we would have willingly excluded ourselves from this eternal love.
All because we did not take the time to find Him in this life.
