To be a Christian with good reputation

Acts 27:38-44
The soldiers planned to kill the prisoners to prevent any of them from swimming away and escaping. But the centurion wanted to spare Paul's life and kept the from carrying out their plan.
In this way everyone reached land in safety.
When the ship runs aground, all make it safely to shore on an island they discover to be Malta.
Why?
Paul was be respected by the centurion, for Paul's life shows the honor of the Lord and he is benefit to those around him.
Paul not only saved his own life but also saved the other prisoners, for a Christian should be like Paul has good behavior and won the reputation from the world.
How?
By the Holy Spirit I can live out the holy life to get the reputation from men around me.
