Human existence cannot exist without all three elements. Motion is inter-dependent on time because actions, thoughts, and feelings cannot take place in this physical universe without it. To go from point A to point B requires a durative period of time. To think through a problem or about something also requires a durative period of time. Action is linear, not punctiliar.
Motion is progressive.
It requires time for it to be performed. Time is part of God's creation, just as squirrels, trees, mountains, and people. Just as God interacts with the rest of His creation, He interacts with time. Because time is created, it precludes God from having His existence rooted in, and bound by time. These three aspects are three divisions of time that we are consciously aware of.
