But how can this "weaker partner" be an appropriate helper?
Take a look at the meaning of "helper". In Hebrew language "help" is "eezer". Abraham had a servant named Eliezer, for he said, "My father's God was my helper" Exodus 18:4. Also Samuel took a stone and named it Ebenezer, saying, "Thus far has the LORD helped us" (1 Samuel 7:12) , recognizing this way the Lord's help.
