“I am afraid
That I have labored
Paul said, “I am afraid (φοβοῦμαι ὑμᾶς) that I have labored (κεκοπίακα) for you (εἰς ὑμᾶς) in vain (μή πως εἰκῇ).” Paul was afraid for them. He was worried that he had labored with them in vain. He thought that all his good Christian work with them was useless. They had become pagan Jewish people instead of being Christians, or followers of Jesus Christ. Are you a real follower of Jesus Christ?
