Is there anything in the Bible to prove that religion must be in agreement with our reason?

Answer by George Townshend:

Yes. Isaiah shows that God Himself wishes man to reason with Him. “Come now, and let us reason together, saith the Lord ..." (Isa. 1:18)

Peter, too, wrote ". . .be ready always to give an answer to every man that asketh you a reason of the hope that is in you . . .” ( I Pet. 3:15)

Paul likewise wrote, "Prove all things: hold fast that which is good." (I Thess. 5:21) He acted accordingly himself when "...he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks." (Acts 18:4), and again when he "...three sabbath days reasoned with them out of the Scriptures." (Acts 17:2)

Jesus Christ taught men to use reason to support fait h when He said, "Wherefore, if God so clothe the grass of the field , which today is, and tomorrow is cast into the oven, shall he not much more clothe you, O ye of little faith?" (Matt. 6:30) (Also see Luke 12:27)

The story of creation in Genesis

… we read in Genesis, in the Old Testament, that the lifetime of creation is but six thousand years. Now this has a meaning. This is not to be taken literally. For instance, it is said in the Old Testament, in the first day such and such a thing was created -- in the first day! Then the narrative shows that the sun was not yet created! How could we conceive of a day if there were no sun created? For the day depends upon the existence of the sun. While no creation of the sun was yet made, how then was the first day realized? Therefore, these things have significance other than literal. (‘Abdu’l-Baha, from an address given at the Theosophical Society, 2228 Broadway, New York City, December 4, 1912; Star of the West, vol.
