When the concept of God is removed something has to replace it. Who determines what government should be, the people, the rulers or the ruler? It then becomes who has the most power.
If all people are equal then all people must be protected. It then becomes the government’s responsibility to care for all my bodily and emotional needs; to clothe and feed me. It then is the government’s job to richly and daily provide me with all that I need to support this body and life and if there is no God and we are all equal then all people should be cared for and protected in the manner they desire. This just cannot work.
If only we had someone that had infinite resources, wisdom, and compassion who could step up and serve all of us. Oh, that would be Christ Jesus, the son of the living God.
