Calvinism teaches that God has sovereignly planned and brought about every meticulous detail, including the evil intentions of His creatures, in order to glorify Himself.

When discussing Romans 8:29 Calvinist’s will typically argue that a personal intimacy is in view.
Calvinism teaches that God foreknows because He decreed that man would act a certain way, and thus man necessarily acts a certain way and God can be certain of that.
To declare God’s glory is to talk about His greatness. God is great, and He is more than worthy of all praise and glory.
