God causes all things to work together for good. For those called, who love him, their purpose is understood. God knew us beforehand, saying we're to be like His Son, that we'd be made His family that comes after the One.
After having chosen us, He calls us by our name and tells us we've been justified, removing all our shame. After justifying us, He stays with us until His work is done, then just for fun, He glorifies us still!
Now what in the world could anyone say in hearing this good news? "When God is on our side like this, there's no way we can lose!"
