First we will look back on the life of Moses, then we will reflect on our own. Life is short. In the day to day, sometimes it can feel long and hard, but if we let ourselves get caught up in the busy moments, we can easily lose sight of what's most important. The hard times don't last forever and neither do the good. When you look back on your time in school, it really was only a small portion of your life. When your children graduate and move out, you say "it all went by so fast." I assume that if we live to be 100 years old, we will say that it all went by so fast. So, we need God to teach us to number our days, so we can grow a heart of wisdom. We don't want to waste this life! But most importantly, we don't want to live it without Him. His blessings are so sweet and His love, comfort, forgiveness, guidance, and perspective is so needed. Not to mention, that one day, we will answer for our time here. If we have spent our life on earth with Him, we will spend eternity with Him. But if we live without Him here, we will live without Him forever.
