The image of the world above details how far God will go to forgive our sins. The verses from Psalm 103 also proove that God's word and the Bible are true.
If you travel around the circumference of the globe in one direction, either east or west, you will always keep to that bearing and never meet the other cardinal point. The same does not apply for north and south where there are poles. You can travel from north to south and when you reach the south pole the only direction you can travel to is north.
Therefore east can never meet west and a loving God has shown us, in this one verse, how far He will go to remove our sin. Amen.
