"We have children because love overflows. I believe as a Christian that I am created in the image of a God who is Love, a God whose love so desired an object that it brought us into being. Although the wisdom and power of love within us is clouded and twisted by sin, still the image of Love is there. We have children because love is essentially creative, and because our souls long for other souls we can love lavishly and forever.
Love precedes the beloved. That is why it is unconditional. In bearing children we participate in God's continuing creative act, and in sustaining and guiding and sacrificing for our children we reflect God's redemptive act. Theologically, then, we have children because we are made after the image of a God who had children, a God who is irreducibly relational and endlessly creative."
