Background: Paul is speaking to Titus, asking him to identify overseers (bishops) in the Churches of the cities on the Island of Crete. This verse is end of the characteristics that qualify them.
How should Overseers build up while convincing those who contradict of their error? This evidence of having oversight is when one has used his knowledge of the Word of God and has used sound doctrine (teaching) to edify (build up) the critic and to convince him of error.
Give an example of what should NOT be done during a staff meeting. Why should it not be done? It simply leads to bitter feelings: nothing positive can come out of it.
What reflection we can glean out of this example about the Saducees? The Saducees, who did not believe in resurrection, were forever plying their hidden agenda before everyone and convincing nobody. They were patronizing and their motives were transparent to others. Let this not happen to a believer.
In their desire to see Jesus Christ crucified, what tactic did the Jews resort to? They perverted justice by using politics and treason as reasons to accomplish Christ’s death.
Why were the Jews filled with envy? Paul was not preaching Christ Jesus to them only, but to the Gentiles! Their strategy changed into opposing and speaking against the Word of God.
