Anything that can be acknowledged in the present, exists. However, there is more to life than that. It's not enough to just be in existence. Man's purpose is to live. Jesus came so that we may have life in abundance (John 10:10).
Living takes nourishment; a source of sustenance necessary for growth, health, and good condition. Sustenance like food and water are natural means for maintaining life. Man's life sustenance, however, is more than food and drink. It is written "Man shall not live on bread alone, but on every word that comes from the mouth of God. (Mathew 4:4).
Eat God's Word for Abundant Living
