LISREL: good model fit, just 1 sign relation. Meaning?




I have tested a theoretical model with 4 hypothesized relations in LISREL. I find a good model fit, but only 1 significant (but weak) relationship. The other relations are nowhere near significant. What does this mean?
With the model as a whole showing a good fit, can I say that the variables predict the outcome variable as hypothesized? Or not, because the relations are not significant? But what does the good model fit then mean?

Advice needed! Thanks in advance.
