Mormon 9:10

And now, if ye have imagined up unto yourselves a god which doth vary, and in him there is shadow of changing, then have ye imagined up unto yourselves a god which is not a God of miracles.

If you have made up a god who does change, then you have made up a god who does not do miracles.

If you’ve imagined a god who changes, who casts a shadow of variation, then you’ve made up a god who doesn’t work miracles.
