I have listened to Calvinists state that all that happens in time is a result of God's divine decree. Where in Scripture do we find evidence for the existence of such a decree, or where in Scripture can the existence of such a decree be inferred?
Not that I am a Calvinist, but perhaps these may be some examples:
The LORD of hosts hath sworn, saying, Surely as I have thought, so shall it come to pass; and as I have purposed, [so] shall it stand:
For the LORD of hosts hath purposed, and who shall disannul [it]? and his hand [is] stretched out, and who shall turn it back?
