Eine wichtige Unterscheidung zwischen Schöpfer und Geschöpf liegt im Unterschied von Sein und Werden.
The difference between the Creator and the creature hinges on the contrast between being and becoming. All that is creaturely is in process of becoming. It is changeable, constantly striving, in search of rest and satisfaction, and finds this rest only in him who is pure being without becoming. This is why, in Scripture, God is so often called the Rock (Deut. 32:4, 15, 18, 30, 31, 37; 1 Sam. 2:2; 2 Sam. 22:3, 32; Ps. 19:14; 31:3; 62:2, 7; 73:26; etc.). We humans can rely on him; he does not change in his being, knowing, or willing. He eternally remains who he is. Every change is foreign to God. In him there is no change in time, for he is eternal; nor in location, for he is omnipresent; nor in essence, for he is pure being.
Herman Bavinck. Reformed Dogmatics, 2:156
