The providence of God may be defined as His guardianship and care for His creatures and creation. Also, any manifestation of such care may be described as providence.
"There is probably no point at which the Christian doctrine of God comes more into conflict with contemporary worldviews than in the matter of God’s providence. Providence means that God has not abandoned the world that he created, but rather works within that creation to manage all things according to the “immutable counsel of His own will” (Westminster Confession of Faith, V, i). By contrast, the world at large, even if it will on occasion acknowledge God to have been the world’s Creator, is at least certain that he does not now intervene in human affairs. Many think that miracles do not happen, that prayer isn’t answered and that most things “fall out” according to the functioning of impersonal and unchangeable laws."^^

Concurrence is "[a]n aspect of God's providence whereby he cooperates with created things in every action, directing their distinctive properties to cause them to act as they do" (Wayne Grudem's Systematic Theology).
