The apostle says to forget what is behind and press toward the high calling of God. Now i believe the apostle was not just talking about visual past but word form. Lets discuss the memory. Now this is a very inconsistent part of our experience. So we can say that a corrupted memory is not to be trusted. In the 70s there was a big push by the elites to focus on the memory as the mechanism for changing the way a person felt about themselves in the present. Let me say this that in all of history including the biblical ot history this kind of approach was never practiced. One is because it is a failure to communicate in word form as the mechanism for growth.

Now let me explain my thinking on this. In my experience we have two kinds of memories. We have a short term memory and a long term memory. The short term memory is not the caboose of the intellect. It is like the conscience that is not taught. It will not be dependable. First because the short term memory only deals with mostly what happens in the physical world. It is not directly related to the accumulation of knowledge but only is limited to the sense orientation. The misery of the human experience is when a person lives their lives as a form of communication on short term memories.
If the apostle was saying for us to forget what is behind then he is talking about a totally different kind of transformation than teaching the memory is the cause of change. lol He is introducing the function of the long term memory. This long term memory is what is the caboose of the experience. Because it is where is the agency of knowledge. This is why the apostle prays that the eyes of our heart will be opened and we will grow deep in the wisdom and knowledge of Christ. So the apostle is distinguishing between a reprobate who lives in the physical memory as his basic way of communicating and the righteous how have a transformed long term memory that creates a lost of bad memories. lol
Now this is what most people have no experience in. They just accept the truth that other people say as the gospel and they have no internal mechanism to draw from that exposes this and must be thrown out. But this is why we have this secret life of God in the soul of man. Deep calls to deep.. God calls the things out of the deep. The Spirit knows the deep things of God and He communicates in His language these things that we do not know quite how to articulate in prayer.
Now if we are led along by our short term memory then we will be most miserable. The mind is like a child that is hungry.. like a deer that is thirsty. It demands deep thoughts and long muses. It does not prosper in short term titillating sensual experiences. Its ani intuitive to a person . If they want to save their lives they will lose them. What is this ... its being led along by yesterdays visuals..lol
What we need to do is drive those worthless short term experiences out of our short term memory so that we only remember His work of transformation. This experience is that He will be our all in all. He will make our lives a testimony of His grace. Our memories of this earth will still be available but it will take thinking very hard to remember them. Our memories are the seeds of destruction that are made to be a self inflicted world view. We can dwell on the wrong things and be driven to live our lives in a sensual way or we can find the glorious illuminations tucked away in our long term memories that lead us to an eternal perspective. Dont waste your time in training in short term memories ... your sensuality will be your misery.
