"Why do you suppose God needs people to speak for him? Why can't your God speak for himself? Audibly? Where I and everybody else in the room can hear him?"
He did speak audibly to Israel when He gave the Ten Commandments, and the Bible says that Israel was so fearful they pleaded that He no longer speak to them. He did speak on the Mount of Transfiguration and terrified the disciples. When He spoke audibly to Jesus, the people thought that they heard thunder.
Sounds like God has a well-established history of speaking. Tell us again why He no longer does so, especially since He continued after Israel pleaded that He discontinue the practice.
So why didn't God just whisper on these occasions? Perhaps He did.
Yes, because God has so much difficulty modulating His voice. An omnipotent Supreme Being, and He can't speak in an indoor voice. And He's no good with money, either. He's always asking for more money.
However, God (in His infinite wisdom) has chosen what the Bible calls "the foolishness of preaching" to speak to humanity. He has condescended to use man to deliver the message of everlasting life to man.
Wow...sounds exactly what a con man would say to convince the marks to fork over their cash. "I speak for the Lord God, because if He spoke directly to you, His awesome voice would overwhelm you! Me, I'm immune for some reason...but you....man, trust me, you don't wanna hear His voice! It's super loud! Now, the Lord God has instructed me to tell you that He needs your money...He's got plenty of everlasting life, but is short on cash, and is looking to make a deal..."
There you have it--the offer of everlasting life. Take it or leave it.
I'll pass, thanks.
