What was God doing before he made heaven and earth? … if (God) did nothing, why did he not continue in this way … forever … ? If any new motion arise in God, or a new will is formed in him, to the end of establishing creation which he had never established previously … then (God) is not truly … eternal. Yet if it were God’s sempiternal will for the creature to exist, why is not the creature sempiternal also?
— Augustine, Confessions
