Often we hear that God's truth is timeless, and that's true. Timeless as in going beyond just the time in which it is written. For example in any time and place, I would think that John 3:16 is pretty straightforward, and requires little or no new special nuancing, to be understood.
But truth needs to also be spoken of as timely. In other words, truth is communicated to us in our contexts in ways that not only resonate with us in helping us understand, but which also moves us towards God's goal of the kingdom in the new creation in Jesus. For example not only are masters told to do well to their slaves in Scripture, but also within Scripture we believe there are powerful seeds planted which in the end do away with all slavery.
Truth doesn't change, so in that sense it's timeless. We need the entire will of God given to us in Scripture, but it takes on different emphases and can be shared and lived out in fresh creative ways depending on the context where we live. Although all of Scripture is the word of God, there are times when certain things in it will jump out at us as needed as a word aptly/fittingly spoken for the occasion, time and place.
Timeless truth in Jesus remains. How it is lived out must ever be subject to new and fresh ways of both speaking of it and living it out. In other words we need to be timely and fitting in our ways of expressing and applying it. I think Scot McKnight is right, that we must not read Scripture through Tradition (whether Eastern Orthodox, Roman Catholic or Protestant Reformation) but with Tradition, always open to new ways God may be giving us both to see and express the truth given to us in Scripture and in Jesus.
I get a sense this is a bit fuzzy, so I'll keep working on it. Maybe it's just this early hour in which I'm up. But what would you like to add to this, or what questions might you have here?
