It wasn’t always like that…
Aspirations for the motto arose surrounding the turmoil and heightened religious sentiment that existed during the Civil War. The Reverend M. R. Watkinson, as part of a campaign initiated by eleven northern Protestant Christian denominations in a letter dated November 13, 1861, petitioned the Treasury Department to add a statement recognising “Almighty God in some form in our coins.”[7] At least part of the motivation was to declare that God was on the Union side of the Civil War.[8] According to Brian Burrell, the actual wording of the motto was inspired by a Union Civil War unit’s company motto.[9][10]
Treasury Secretary Salmon P. Chase acted on this proposal and directed the then-Philadelphia Director of the Mint, James Pollock, to begin drawing up possible designs that would include the religious phrase. Chase chose his favorite designs and presented a proposal to Congress for the new designs in late 1863.[11]

It wasn’t always on the pledge of elegance either.
