The first song that I remember learning in church was the Doxology, the “word of glory and praise”, from the Greek words doxo, meaning “glory“, and “logos“, meaning “word or reason“. And Marshall Brain, the mind behind “God is imaginary”, encourages us to listen to it in proof 23.
“Praise God from whom all blessings flow,
praise Him all creatures here below.”
“Praise Him above ye heavenly host,
praise Father, Son, and Holy Ghost.”
“With that one sentence we can prove that God is imaginary, just like Santa Claus.”
Well, aside from the category error there Marshall, no we can’t. God gives life, intelligence, means, and as Jesus phrased it in Matthew 5:45 (NKJV):
“[…](God) makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust.”
Santa, just gives presents to those who believe in him once a year (that’s just me being snarky).
Let us suppose that God is real and that all blessings actually do flow from him. If that is the case, then the utter unfairness with which he disperses his blessings is proof positive that God is ridiculous.
Marshall, God disburses His blessings with absolute fairness. If you measure fairness by material blessings, you are missing the point. How a person acquires those things come from a variety of factors that are dependent upon the person, not the God who gives. Every person that is born is born in a place and a time that God chooses to place them, with the same opportunities of anyone else in that place and time. A lazy man will founder, a man who is industrious and able will succeed, that is just the nature of the world.
The point of that little hymn that gets sung in congregations of believers around the world is to remind the believers from whence came the greater blessing: the ability to come before God, that being the life, death, and resurrection of His Son, Christ Jesus. That through Christ, all to whom He shows His grace to, have right standing before Him. It’s something that we are grateful for. But for someone who hates God, they cannot humble themselves, they cannot worship Him, they cannot praise Him.
Your question about the church, maybe they had good investments that paid off, or wealthy members that contributed heavily, but as I said here, I agree that churches can go too far and lose their purpose and focus. While there are millions of people around the world starving tonight, it has nothing to do with the blessings that you, and a lot of other people, have confused with stuff, rather than the knowledge of who God is and what He has done for His people.
