In what ways had Paul been proven to be a servant of Christ—ways of which the Jewish false apostles knew nothing because they were seeking their own gain?

In strenuous work more often than the false apostles.

In innumerable whippings.

In prison more frequently.

He had often faced death.

Five times at the hands of the Jews he had received thirty-nine lashes.

Three times he had been beaten with rods.

Once he had been stoned.

Three times he had been shipwrecked.

He had spent a night and a day adrift in the sea.

He had been on frequent journeys.

In danger from rivers and floods.

In danger of robbers.

In danger from his own race.

In danger from the Gentiles.

In danger in the city.

In danger in the desert.

In danger in the sea.

In danger among false brothers.

In labour and hardship.

In long prayer-vigils often.

In hunger and thirst.

In fasting often.

In cold and nakedness.
