Nothing whatever, whether great or small, can happen to a believer, without God's ordering and permission...There is no such thing as "chance," "luck" or "accident" in the Christian's journey through this world. All is arranged and appointed by God. And all things are "working together" for the believer's good.
"We know that for those who love God all things work together for good, for those who are called according to his purpose" (Romans 8:28).
"Christ is the one "who opens and no one will shut, who shuts and no one opens" (Revelation 3:7).
