An omen or sign can bode well for someone's future.
The word "bode" is often used to talk about signs that show whether something good or bad will happen. For example, if there are clouds gathering on the horizon and it looks like a storm is coming, that might bode poorly for your outdoor plans. But if you see birds flying happily around your garden, that could bode well for a nice day ahead. In general, when we say something bodes well or ill for someone or something, we mean that it's giving us some kind of hint about what will happen next.
An omen; a foreshadowing.
To indicate by signs, as future events; to be an omen of; to portend or foretell.
