Hello,
George Washington didn’t write the Constitution, the Congress did. His signature appeared on it, but how do I know that it wasn’t forged. Congress probable just made up George Washington to bolster their claims of a new nation. Currency, paintings and statues are just artwork, not a living person - an artist’s imaginative work copied by future artists.
Parallel:
God didn’t write the Bible, but inspired it - George Washington didn’t write the Constitution but inspired it, particularly in using a presidential system rather than a monarch system. God did, though, physically write the two tablets containing the law given to Moses. And we can say that He signed the Bible with His approval when He guided the Councils that defined the Canon.
We have more than just paintings and statues of Jesus (though we have those, too). We have the Shroud of Turin and the Veil of Veronica that bear His likeness from His Blood. And we have:
O.K. Take two aspirins and call me in the morning.
