God, in His foreknowledge, has always known the plan and revelation of the new covenant with all its details. So, in the Old Testament, He shows in picture form, in types and figures, what would soon come to pass in reality.
The feasts, the sacrifices, have all shown the beauty of what was to come in the new covenant. We no longer are only able to see the picture, we have the real thing. Even though one may now be enjoying the presence of a friend, one does not throw away the pictures of them. The same with the feasts. We can enjoy Passover while rejoicing in Jesus, with Jesus. He is now present with us, in us, while we celebrate the reality of His death, resurrection.
Just as those pictures of an absent loved one, is treasured and often viewed, while awaiting that one’s return... so a type in the Old Testament, showed the image of what was to someday come in reality. The reality is the truly valuable and loved... as a lamb on the altar of burnt offering showed in type the sacrificial nature of Jesus. When Jesus came, the lamb, though a beautiful picture, is not preferred to the reality of Jesus.
Yet, the picture of the lamb, is a beautiful way to teach the reality of Jesus’ nature and work for us. We can view in clearness, His way and manner of approaching the sacrifice He gave for us. Typology should not replace the reality, but should make the reality more clear, more understood.
We miss much if we do not get the groundwork of typology correct. It can also be related to the foundation of a building,... and to have a good foundation in typology, strengthens the beauty and reality of the structure upon such foundation.
Understanding the feasts aid in understanding the truths of their fulfillment. We see the various elements explained in the types of feasts, and rejoice then in realizing their reality in the arrival of Who they prefigured. This is not sinful. It was meant to be an 'example', a lesson to be learned.
There are two kinds of truth in Scripture.
Hebrews 5:12-14
“For when for the time, ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat. For every one that useth milk is unskilled in the word of righteousness; for he is a babe. But strong meat belongeth to them that are of full age; even those who by reason of use have their senses exercised to discern both good and evil.”
Milk and meat... are one way to describe truths in the Word. Meat represents the deeper truths, and milk represents the basic, simpler truths. Typology contains both, and yet, by its nature, it is like a bridge, to carry us from the milk to the meat... It takes a truth, puts it in simple form, and then allows, or encourages, deeper seeking into that ‘milk’ truth, to find a ‘meat’ revelation.
I Corinthians 10:11
“these things, written for our admonition’
Hebrews 8:4-5
“Who serve as an example and shadow of heavenly things”
Hebrews 9:8-9
“which was a figure for the time present”
Hebrews 10:1
“... law having a shadow of good things to come...”
The words ‘shadow’, ‘example’, ‘pattern’... all contain the idea we refer to as ‘types’. Types are used to prefigure some person, thing, or event that would appear in the future. Types are a ‘sort of’ prophecy. Prophetically, types show us what was to come.... and the type shows the foreknowledge and planning of an Almighty God.
I celebrate Jesus in the Passover season. I do not normally follow the Passover dinner type, but I find no fault in those who do. I rejoice in the reality now present that was shown in the picture of Passover. The same for the 'feast of tabernacles', and Pentecost, etc... They are wonderful pictures, and as long as we realize that Jesus is the fulfillment, the reality of what they prefigured, we are safe to value the beautiful pictures that God provided.
I don't find you sincere, nor likable. From my point of view, judging from your posts here. I find sarcastic inuendos and puffed up pride coming from both you and frog. You should be a shamed that 'others' find your appearance this way. If it were one troll calling you out I would think the troll is stupid. But we have numerous posters from all across the board telling you the same thing. Straw man arguements. When this gets identifed to you guys you pull the pal card. 'stop being personal with me and deal with the text'. All the while being personal with others and NOT dealing with the text honestly. As proven by numerous 'others' from across the Christian spectrum.
