2 Peter 1:2-3

2 Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord; 3 seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence.

Here Peter wishes, or prays for those he is writing to that grace and peace would be multiplied to them, and that it would be in proportion to the knowledge they have in God. Hence, he desires that they have a strong and deep knowledge of God. The Greek word here for knowledge, epignoosis, is a precise and correct knowledge—knowing the truth about God and knowing the difference between right and wrong. It is a more intimate and advanced knowledge. It is a knowledge that can become deeper and more intimate according to ones time with God and His word. Hence, the more intimate it becomes the more grace and peace would be multiplied to them.

From verse three, Peter writes that everything pertaining to life (the Christian’s eternal life) and his godliness (his ability to live a pure life) can and will be given to him if he has a true knowledge of God. And I take it that it is up to every Christian to develop his own knowledge of God by prayer, the study of the word, and obedience to God.
