Could not agree more. John 5:39There do appear to be distinctions in the Pentateuch. The ten commandments would be 'categorical law', the foundations of societal harmony. The rules that follow these in Exodus read more like judicial guidelines. And then there are the levitical regulations which deal more with the maintenance and continuation of the nation's relationship with God. But some passages aren't so clear cut (and there are probably parts that can be categorised in other ways).
But it foreshadowed the Christ, it echoed the One who was to come - as you already know. When I open the feasts, for example, in Lev 23, I see God's timeline in human history. I see God's promises in Christ.
When I read God commanding the Israelites not to sin, I hear God telling me that He's empowering me not to sin. I hear the commandments as promises - written within, empowered by the Holy Spirit, fulfilled in Christ in me.
We don't follow the external written code that condemns and kills - we live in the promise and walk in the fulfilment. We're no longer sinners, we're saints - obedient to God through the presence of the power of the resurrection (and don't forget the ascension, of course).
Sorry - going on a bit. It's a shame that we don't get high on the fulfilment but have to deal with the idea that we're gathered round Moses at Sinai all over again.
"You diligently search the Scriptures because you think to have eternal life in them, and these are they bearing witness concerning Me...." (Berean Literal)
We are saved according to God's foreknowledge; predestined, called, justified and glorified. And that to be conformed to the image of God's Son - not the Law. (Romans 8:30)
Don't worry about going on a bit. What you have to say is worth hearing. I can't say the same for every poster here.
