Imagine you have a compass. If you travel northwards, you will eventually reach North Pole and you cannot go northwards anymore as you have reached the endpoint for North. The same goes for traveling southwards – you will eventually reach South Pole and you cannot go southwards anymore as you have reached the endpoint for South. However if you travel eastwards, you will never reach an endpoint. It is the same for traveling westwards – no endpoint.
The above is an illustration that the pastor used recently to explain PS 103:12 – “As far as the east is from the west, So far has He removed our transgressions from us.”
It took me a while to understand the illustration. Basically, the distance between North and South is finite and measurable as there are 2 fixed endpoints. But the distance between East and West cannot be measured as there are no fixed endpoints. This illustration gives me a new understanding to the verse. Previously I understood “as far as the east is from the west” to imply a very long distance apart, now this illustration shows that this distance is so long that it cannot be measured. Apply this enhanced understanding to PS 103:12, the verse is saying the Lord has removed our transgressions, and placed them so far away from us that the distance in-between cannot be measured. Or, our transgressions are removed and placed X km away from us, where X = infinity.
