See C.S. Lewis The Four Loves, specifically his discussion of “Need-Love” starting at “But thirdly, we come…” in the Introduction.
“He lacks nothing, but our Need-love, as Plato saw, is ‘the son of Poverty’. It is the accurate reflection in consciousness of our actual nature. We are born helpless. As soon as we are fully conscious we discover loneliness. We need others physically, emotionally, intellectually; we need them if we are to know anything, even ourselves.” -C.S. Lewis, The Four Loves
“It is one of the greatest blessings of mankind, though many denounce it as a curse. Not only does it touch the deepest springs of man’s life, but it also controls his thoughts and feelings and desires.” -Louis Berkhof, Summary of Christian Doctrine
“Religion without faith is a deadly thing.” -R.C. Sproul
The world is “the primary context for spirituality.” -Eugene Peterson
BTW NOTE: This is due to the fact that most of our life is lived in the world, outside the doors of the church.
“Tragically, religion and spirituality provide a whole toolbox for avoiding Jesus today.” -Michael Horton
“Rather than court absurdity, however, let us graciously grant that there is indeed such a thing as unthinking religious conviction, just as there is a great deal of unthinking irreligious materialism. Let us also, more magnanimously, grant the truth of the second conviction I attributed too these writers above: that religions is violent, that religion in fact kills. At least, let us grant that it is exactly as true, as intelligent significant, as the propositions ‘politics kills’ and ‘color reddens.’ For many thing are true in a general sense, even when, in the majority of specific cases, they are false.” -David Bentley Hart
