2 Peter 1:2
Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord,
Grace and peace can be multiplied in your life and this can be done through the knowledge (Grk. Epignosis), of God and of Jesus our Lord.
Epignosis - Absolute knowledge that comes through revelation and relationship.
Therefore, to multiply grace and peace in your life, you've got to know more of God.
