I posted at Out of the Ordinary this morning on what it means that God ordains whatever happens, and what difference this makes.
When we use “ordained” to describe an event in history, we mean that God put it in his plan and then unfolded things, including this event, according to the plan. Ordained history consists of ordained causes and effects, all in their proper places, chained together, tugging forward toward God’s planned completion. It’s the same for the future; the ordained future will unfold and then wrap up just as God intends.
