I agree (& with the further omitted part), but the terminology
may be confusing. Hollaz (17th cent Lutheran) defines concurrence as
"Concurrence, or the co-operation of God, is the act of Divine
Providence whereby God, by a general and immediate influence,
proportioned to the need and capacity of every creature,
graciously takes part with second causes in their actions and
God's action is "immediate" (or direct) in the sense that God is
immediately present to & active with "every creature" in all its
actions. God did not simply wind things up in the beginning in such a
way that that creature would do a particular thing at a particular time,
as deism says. (It is concurrence rather than precurrence.) But God's
action takes place with & through the creature, and in that sense is
mediate or indirect. & what we observe scientifically is the creature,
not the God who works with & through the creature.
Traditionally providence was divided into sustenance,
concurrence, & governance. The 1st is what Eduardo notes, that God
keeps things in existence. When people saw the world as consisting of
things with more or less static natures, this was given priority over
concurrence. With the dynamic picture of the world which quantum field
theory gives, concurrence (or co-operation, God "operating with"
creatures) has to be at least an equal partner. In a real sense
substance is interaction (m = E/c^2).
