God is not simply the subject of contemplation in the sense that a metaphysical philosopher undertakes to reflect upon God and in the way God truly knows himself, and as we in the next life shall come to know God more fully (1 Cor 13:9, etc.; 2 Cor 12:4); but in the sense that to know Him in this life is what we have to do in order to obtain eternal life by truly knowing Him (John 17:3).
