In special theory of relativity, each event is a point in 4d space-time. And we can represent our life as a world line in the space time. Then, if we somehow find out the mathematical equation of somebody's world line, then can his future be predicted?

If you have the mathematics of a moving body its future is predictable in classical mechanics. It would be the same in the extension of special relativity though for a person it is a big IF.
Nature though is not classical, classical emerges from an underlying level of quantum mehanics, which is inherently probabilistic. There fore there is no mathematical equation of somebody's world line. One could fit a world line up to the present after the fact, but the future is probabilistic because of the Heisenberg uncertainty.

As Anna v has pointed out, this is not something unique to SR. Even classical physics allows for us to "predict the future". Anna's answer gives why this is unreasonable due to QM, but even if that could be overlooked (it can't though), there are other problems.
You are made up of cells, which are made of molecules, which are made of atoms, and so on. To predict your future you would need to know the world lines of all of your parts. All of your biochemical reactions and decisions would need to be predicted (assuming that your decisions can be determined from the interactions of these different parts, but biology is very complex, so this is pretty much an impossible task already). You (I'm assuming) interact with others on a daily basis, so you would need to do this for then as well. But they interact with others as well. And on and on.
So really it's impossible to predict the future this way. It doesn't come down to finding a single math equation for a single world line. I would say you have better luck consulting a psychic at this point.
