I have spent many long hours in the hot sun practicing for just one football game. All our efforts in that week were geared to a three hour period on Friday night. The proportion of practice time to game time might seem disproportionate, but the preparation is essential. The reality is that we can't succeed on the Friday night playing field without diligent effort on the practice field during the week.
Spiritually, the same principle applies. We will spend far more time in training than we will in actual competition. We will have opportunities to engage the enemy, fight for the souls of our children, and pray fervently during threats to our families & friends. We won't be successful if we haven't spent the necessary time preparing for the actual event. If we neglect the practice phase of preparation we're not as good as we think we are and will be quickly defeated once the real competition begins.
