In the Bible, God often uses types to teach us truths about the things represented by the types(the antitype). For example Isaac was a 'type' of Christ, in that he foreshadowed some aspects of the Messiah. Here is a link to a list of verses that show this relationship: http://www.bible.org/illus.asp?topic_id=1606 This type is very deep and exposes a lot of information that was hidden in the scriptures. There are many types of Christ throughout the Old Testament, as well as other types. Heb 8:5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount. God is very protective of the types that He has established, the tabernacle being an example. God has revealed more of His son in the tabernacle, and it was imperative that these types be preserved when the tabernacle was constructed. Thus the admonition to follow the pattern that Moses was given. If Moses had changed anything in the construction, the type would have been affected. Moses got in trouble for messing up one such picture of Christ, when he struck the rock twice instead of speaking to it as God commanded him. The rock was a picture of Christ, who was to be smitten once as sacrifice for our sins. Afterward, God told Moses to speak to the rock, which was a picture of us coming to Christ who is now our advocate, making intercession for us, and confessing our sins and asking for forgiveness. He does not have to be sacrificed again. For disobeying God in this matter, Moses was not allowed to enter into the promised land. Numbers 20 8 Take the rod, and gather thou the assembly together, thou, and Aaron thy brother, and speak ye unto the rock before their eyes; and it shall give forth his water, and thou shalt bring forth to them water out of the rock: so thou shalt give the congregation and their beasts drink. 9 And Moses took the rod from before the LORD, as he commanded him. 10 And Moses and Aaron gathered the congregation together before the rock, and he said unto them, Hear now, ye rebels; must we fetch you water out of this rock? 11 And Moses lifted up his hand, and with his rod he smote the rock twice: and the water came out abundantly, and the congregation drank, and their beasts also. 12 And the LORD spake unto Moses and Aaron, Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them. Seeing that God puts such emphasis on pictures and types, what are some other pictures that we can learn from, and how much can we rely on types to teach us about their antitypes?
