I used to fly small planes here and there across eastern part of Australia. It was an exciting period of my life where I had the chance to get my PPL (Unrestricted Private Pilot’s License). It was in the days before GPS and we had to navigate by DR (strictly speaking Ded-reckoning but commonly referred to as “dead reckoning”). The ‘ded’ referred to “deduced” reckoning. That is, working it out using known information. It was always a terrific challenge to fly exactly along the track you had made on an aeronautical map. It’s hard to imagine getting lost while you are five or six thousand feet above the ground, but it can happen. My brother-in-law told us that when he was learning to fly the instructor told him if he was on a cross country flight and became lost and if there was a railway line somewhere close he could fly along the railway line as low as he was allowed to so that he could read the sign at the next railway station. Railway signs were big enough to be read from fifteen hundred feet above the ground. It happened that he did lose his bearings on one such training flight. He saw the railway line, flew slightly to one side of it and got down low enough. The station he flew past and read the location of happened to be Gunning (my home town). He hadn’t heard of Gunning before that day but found it on the map and got himself safely back on track. There was a lovely irony when he laster started dating (and then married my sister) and ended up spending a lot of time on the farm at that location.
Anyway, we would always set out to fly exactly along the track. Sometimes we would find ourselves a few miles to the left or right and it would require a slight adjustment. They had a thing called the one-in-sixty rule got you back on track with not too much lost time.
I can readily understand someone getting a few miles off track. A bit more cross-wind than was forecast was all you needed. I can’t imagine flying in the complete opposite direction to what was intended. Everything instrument and everything you could see would scream at you and tell you what was happening.
You have to be a follower of Jesus to find yourself going in completely the opposite direction to the one intended. You have to belong to the church to be doing that and NOT KNOW ABOUT IT.
One way this happens is when we persist in taking our identity and our reference points from the past. When we do this we can find ourselves defending and protecting the past rather than using the past as it really is – a stepping stone to the future. The past is to be remembered, celebrated and appreciated, but never slavishly replicated, worse still, defended.
This was an issue when the Israelites came back from exile. A little group of passionate believers left the comfort of the rivers of Babylon and the majority of their fellow Jews and risked life and limb trekking through harsh and dangerous country to end up looking at the pile of burnt rocks that was the remains of Jerusalem. When they tried to rebuild the temple it was hard, there was fierce opposition and it was not going to be anything like the one that had stood there before.

We have to finish what we started.
When Zechariah starts getting visions about what God wants to do with Jerusalem and the temple there are more surprises. He gets a vision about the new priesthood. Joshua and his fellow priests are told that they are neither to reflect nor replicate the past but they are to be a sign of the future. That future we are told (Zechariah 3) is to do with the coming of the Chosen King (Jesus).
That’s the way it is always meant to be. Why does it seem impossible for us to appreciate and remember without feeling the need to freeze-frame some moment in history and think that by locking it down we are serving God. Why is it in Christian history that the next reformational movement found their most vicious enemies among the people who were part of the previous most recent reformation movement. We are subject to a deadly virus that says “Let’s keep it like it is” rather than “let’s become more like Jesus.” We seem to be able to find a way to justify doing that to the point where we continue to crucify anyone who just may have MORE. It was true when Jesus was leaving footprints on the earth and it is still true.
Zechariah’s vision involving Joshua and the renewed priesthood was all about the future. God required them to be a continual sign of the future rather than being custodians of the past. I have a serious suspicion that the “good old days” were not nearly as good as they are sometimes made out to be. The challenge for us is not to become endlessly faddish or voguish. The challenge is to use the past and the present as stepping stones to a future that we can discover but never control, one that we can embrace but never possess. The only measure of it will be its capacity to reflect more of the glory that only belongs to Jesus.
Here are some Power Point slides that sum up last Sunday’s teaching.
