'Design' in the Bible

And we know [with great confidence] that God [who is deeply concerned about us] causes all things to work together [as a plan] for good for those who love God, to those who are called according to His plan and purpose.

In Him also we have received an inheritance [a destiny—we were claimed by God as His own], having been predestined (chosen, appointed beforehand) according to the purpose of Him who works everything in agreement with the counsel and design of His will,

but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets.
