Romans 8:28-30 focuses on the idea that God works everything together for the good of those who are called according to his purpose. The Bible holds up Romans 8:28 with foreknowledge, predestination, calling, justification and glorification. The essence of idolatry is the entertainment of thoughts about God that are unworthy of him. We imagine things about God and act as if they are true. Verses like Ephesians 1:4 and Revelation 13:8 refer to God's plans that were in place before the "foundation of the world."
