Considering that it's a divine ability, I'd more describe it as calling upon the power of your patron to bolster your attack. So I would be more suprised if it could not be applied to non-martial attacks.
I assume that one 'build' of paladin is based strength, just as we know rogues have (at least) a finesse build and a thug build. Hence the use of strength bonus fits thematically. I can picture such paladins regarding the exercise required to maintain their strength and vigor as a form of religious devotion.
