Christianity
In Genesis, God creates the heavens and the earth through divine command: “Let there be light.” God creates the universe; the mechanism may be instantaneous or unfold through processes such as evolution and the Big Bang. Science explains how creation unfolded; God explains why it exists.
Many Christian mystics — Meister Eckhart, Julian of Norwich, John of the Cross — viewed creation as a continuous emanation of God’s love, and described it as God’s self-expression.
