This verse clearly has nothing to do with the shape of the earth. Flat or round earth, east is the opposite direction of west.
--Dave
Oh, I am sorry, I forgot that the clarity of what that verse states or rather implies was not obvious to me, many, many years ago until it was explained to me by a wonderful teacher of God's word.
Psalm 103:12 states that as far as the east is from the west so far has he removed our transgressions from us.
If you were on a point on the equator and traveled straight north how far could you keep going until you could no longer travel north? If the earth was flat or round there would be a limit. If the earth is round it would be when you reached the north pole and kept moving on the same direction you would start travelling south. Why because the north pole is the limit that you can travel north on the earth. If the earth was flat, the limit would be when you reached the edge of the earth.
If you started at any point on the earth, not including the north or south pole on a spherical earth, you could travel straight east and never get to the point where you would start travelling west.
If the earth was flat, there would again be a limit as to how far a person could travel east, that limit would be the edge of the flat earth.
If and since, the earth is spherical, God's mercy separates us by an infinite distance from our transgressions.
That is why God spoke of east from the west in that verse.
If he had said as far as north is from the south, then there would be a limit.
That verse wisely tells us that God's mercy is without limit for those who believe.
However, that can only be true if the earth is spherical, not flat.
If the earth was flat, there would be a limit to God's mercy to those who believe.
Question is, who are you going to believe?
a. science falsely so called
b. God's word
If you have trouble with that explanation, you might want to consider if you really want to believe God's word or not.
