According to the passages we read, it is possible for a good man to have his steps order by the Lord while at the same time his foot slips and he falls. But the difference between a good man versus and evil one is that he never stays down. An evil man, on the hand, never repents. He continues the same course.
Abrasion is defined as the erosion that occurs when particles scrape against each other. The enormous weight of the glacier, along with rocks and sediment plucked up and clinging to its belly scratch and carve the rock surface below. It's almost as if the moving glacier is sanding the rocks with abrasive sandpaper.
If they are today exposed at the surface, the only way that could happen is if the granite rocks were uplifted and the overlying sedimentary rocks were eroded. In areas where Earth's surface is covered with sedimentary rocks, granites, metamorphosed granites, or closely related rocks are usually present beneath the sedimentary cover.
