“He is before all things, and in Him all things hold together” (Colossians 1:17).
Instead of engaging in substantive dialogue regarding the historical Christian understanding of God, atheist’s embrace their own unsubstantiated assumptions. Their argument, seemingly, is against a deity that exists as some item on a desktop; that because we are unable to point it out, remove and examine it then it must not exist. A more reasonable understanding is that being the Creator of all things excludes God from this inventory of things. He is the Source and Ground by which all things are held together.
