Building on that theme, E. P. Clowney explained that three dimensions of Christian meditation are crucial, not merely for showing its distinctiveness, but for guiding its practice. The first is that Christian meditation is grounded in the Bible. Because the God of the Bible is a personal God who speaks in words of revelation, Christian meditation responds to this revelation and focuses on that aspect, in contrast to mystic meditations which use mantras. The second distinctive mark of Christian meditation is that it responds to the "love of" God, as in I John : "We love, for he first loved us". The personal relationship based on the love of God that marks Christian communion is thus heightened in Christian meditation. The third dimension is that the revelations of the Bible and the love of God lead to the worship of God: making Christian meditation an exercise in "praise".
