As God has raised Christ to heaven, so God counts the believers in Colossae as though he has also raised them to heaven. "Raised" here is an idiom for "established." AT: "God has established you with Christ" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-idiom]])
To sit at God’s “right hand” is an idiom that means that Christ is ruling as God, with God’s authority. AT: "God has caused Christ to rule as King." (See: [[rc://en/ta/man/translate/figs-idiom]]).
Paul speaks of people's lives as if they were objects that can be hidden in containers and speaks of God as if he were a container. AT: Possible meanings are 1) "it is as though God has taken your life and concealed it with Christ in God's presence" or 2) "only God knows what your true life really is, and he will reveal it when he reveals Christ" (See: [[rc://en/ta/man/translate/figs-activepassive]] and [[rc://en/ta/man/translate/figs-metaphor]])
