Synchronicity may be an experience of divine providence. It may be a sign of God's personal intervention in our personal life; and therefore an indication that our live has purpose, hence meaning.
On the other hand; some synchronicities seem to be meaningless and coincidental, in they seem to make no sense or seem merely trivial - so as to make a mockery of providence: on the lines of: "If God has nothing better to do that that, then what kind of a God is it?"
And apparent synchronicity can be faked (using information gathered through surveillance or 'stalking', for example) and our feelings thereby manipulated; and this can be done by human intervention - or indeed by demonic.
Indeed; I think it likely that a considerable amount of evil is accomplished by strategic demonic manipulations of a synchronistic type - that are intended to lead to sin committed under the delusion of 'destiny', therefore un-repented sin, thus value-inversion.
(This seems to have happened frequently among New Age spiritual seekers, - especially with regard to sex.)
So someone who was to regard all synchronicity as evidence of destiny, could be led into evil.
In other words; synchronicity is not always A Good Thing.
We need to discern synchronicity in our own lives - since, like most things, it may be motivated by evil; as well as being a potential manifestation of Good.
