When the Bible speaks of doing things "forever," does God mean what we mean when we say "forever?" Well, no. What God means is that the person or group to whom He is speaking is bound to something as long as God sees fit. Those today who claim that they embrace ALL of scripture fr themselves fail to do many things God said were statutes FOREVER.

There is a theological word for making distinctions in scripture based on God's instructions for one age that completely change (and may even be sin and a denial of Christ!) in another. That word is "dispensationalism."

Even the most committed and hardcore Reformed Preterist isn't obeying the commands in the Law that God declared "forever." That makes him a dispensationalist whether he likes it or not. We need to apply this understanding across scripture. We don't live based on the Sermon on the Mount, we don't live like the believers in the Acts, and we shouldn't even be practicing the Lord's Supper in this current age.
