In a medium bowl, whisk together the flour, cinnamon, nutmeg, baking soda and salt. Set aside
In a large bowl using an electric mixer, beat together the butter, brown sugar and granulated sugar until fluffy (about 2 minutes).
Beat the honey, vanilla extract and egg into the butter mixture.
With the mixer on low speed, beat the flour mixture into the butter mixture.
Stir in the oats and raisins. The batter will be sticky.
Cover the bowl with plastic wrap, and refrigerate for 30 minutes or overnight.
When ready to bake, preheat the oven to 350F (180C) degrees. Line 2 cookie sheets with parchment paper.
Using a cookie scoop or tablespoon, form the dough into balls of about 1 to 1.5 tablespoons and place 2 inches apart on the lined cookie sheets.
Bake 1 tray at a time, on the middle rack of the oven for 9-11 minutes or until the tops look just set.
Remove from the oven and cool fully on the cookie tray.
