Video from Reformed Forum
"Carlton Wynne discusses Old Testament types and symbols that now only represent but also communicate Christ to believers. Temporal and earthly realities represent something beyond themselves that is fulfilled and accomplished in the person and work of Christ. Vos distinguishes between a type and a symbol. Whereas types are prospective, symbols have reference to the present. This clip is from Christ the Center episode 736 (https://www.reformedforum.org/ctc736)" from video introduction.
