Dave Ramsey is not God. The only time God came to Earth was in the form of Jesus Christ. David Ramsey is nothing more than a financial adviser. The LORD no longer has to come and get our attention. It is the job of Christians to spread His message. If Ramsey was God, his "coming" would have been a spectacular, global event, with a darkened sun, lightning, and his sign in the heavens. Granted, we do not know what the sign will be, but it will be visible worldwide.
Again, if Ramsey was Jesus Christ, he would have in a spectacular event. Second, if he was Jesus, there would world peace, everyone who believes in him would live forever, and those who don't would die at one hundred. All animals would be docile, and there would be no pollution.
Dave Ramsey has provided the miracle of a debt free life to those who choose to accept him. Only a master of the known and unknown can have the powers to give life to a man who is so far in debt that he has given up. That is a true miracle.
It doesn't take a miracle to have his knowledge. You only need the right schooling. There is nothing supernatural about being good with finances. Besides, God's miracles tend to be healings and conversions these days. Wealth matters little to God, and poverty is still life. Getting out of debt does not give one new life.
