Things might happen for a reason. But could you please explain me the reason why they happen?

Things don't always happen for a reason things usually happen because of your reasoning or some one else's.

I'm a believer in karma, and I'm also a believer that things happen for a reason.

I think that things happen for a reason.

Things happen for a reason; and the reason is hidden

It is not REASON vs FAITH, it is REASON vs NOTHING. And the answer is NOTHING!
