How can you multiply peace (and grace) in your life? This verse clearly points out that it is done by knowing God, by knowing Jesus Christ, His Son. You have the Bible, and it is there that God reveals Himself primarily, and all you need to know about Him is revealed in this Holy Book; the bottom line is to read it, to understand it, and then apply it practically so that it may be nurtured inside your heart, to bring fruit, just like a seed.
