“For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified” (Romans 8:29-30).
If he looks at the recent past he finds that God called and justified his people whom he had predestined.
And if he then looks toward the future when Christ returns, he sees that God has determined to give perfect , glorified bodies to those who believe in Christ.
From eternity to eternity God has acted with the good of his people in mind.
But if God has always acted for our good and will in the future act for our good, Paul reasons, then will He not also in our present circumstances work every circumstance together for our good as well?
In this way predestination is seen as comfort for believers in the everyday events of life.”
