Final answer:
The apostles were convinced by the truth of Jesus's resurrection and then transformed, which led to the spread of Christianity. The correct answer is option 2: convinced, transformed.
Step-by-step explanation:
The apostles needed to both be convinced about the resurrection and they were transformed by the resurrection.
After the resurrection of Jesus, the apostles were initially in a state of shock and disbelief. However, witnessing Jesus' return to life and his teachings, they would have been convinced of the truth of the resurrection. This conviction would have led to a transformation in their beliefs and actions.
They started preaching the lessons of Jesus Christ, which contributed to the spread of Christianity. The transformation reflects a shift from doubt to faith and from normalcy to a life dedicated to spreading the teachings of the resurrected Christ.
