Well you say it right concerning the other verses, trying to showcase that the earth is supported, because ideally it is by the law of gravity which God established, but consider this if you were living in the times for which this words were penned, when all ancient civilisations believed that the earth was hanged on something, whether it be the elephant like the indians or other beliefs. Yet we now prove it in our days that the Bible is true only that you also consider that visually it wasn't hanged on anything but equally he has made invisible laws or powers that hold the earth in its place. Let me take you back this are just pointed scenarios about what God said long before science discovered them, Read Genesis 1:24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so, well even this was before any construction of modern science through what we would have considered as an uncertain belief but isn't it what we have as proof today, even against the laws of evolution? Consider also the idea of atoms Hebrews 11:3 Through Faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which do appear. Conventionally in some way we could think of the things that do not appear in scientific terms as atoms, even more is what Peter says in 2Peter 3: 10 But the day of the Lord will come as a thief in the night; in that which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Isn't this from a current class of nuclear physics with the suggestion of the possibility of the energy present in the atoms and if ever the special forces holding the nucleus in place will be let loose then we would end up with a universal catastrophe as predicted? Even so Colossians 1:17, And He is before all things and by Him, all things hold together. Of course science still grapple with the forces that holds the nucleus together and have since called this "super glue" yet He is the one who holds all things together and one day He will let go just as the understanding that we in the 20th century know of.
