Finding the truth not only requires time, but it requires a very large amount of inductive and deductive reasoning. Logic is not always the easiest way to go, but it can help in narrowing the field of options down. There are many overlaps between the two, but not many similarities. Objective truths focus on the beliefs of a society or world as a whole, but the Earth is very diverse and so there are great amounts of objective truths. Religion is a prime example of an objective truth.
Subjective truths focus on the individual and are heavily dependent on the environment of a person.
If a person believes in God and the majority of the people do as well, then it is both a subjective truth and an objective truth. That does not necessarily mean it is actual or proven. Proving truth can most readily be done using mathematics, as Rene Descartes originally proposed. There is no way to disprove this equation, and therefore it is actual as well universal. A universal truth may be subjective and objective as well.
