What is Life?

Life, simply put, is the presence of God,
the greater the presence, the greater the Life.
 
In other words, the closer you draw near to God,
The closer he draws nearer to you,
The greater experience of life, His Life you will see.

Submit yourselves therefore to God.
Resist the devil,
and he will flee from you.
Draw nigh to God,
and he will draw nigh to you.

~James 4:7-8

All of life is all about trinere to God. When you do so you draw near to eternity. You try near to infinity. You draw near to the source of life. The author of life.

The opposite is also true, with the absence of God, you have an absence of life,. To the degree that you have an absence of God to that very degree you have enough sense of life.
