“But stand up and enter the city and you will be told what you must do.”
Saul saw the Lord Jesus on his way to persecute Christians in Damascus. He asked what he should do. The Lord told him. To do for what purpose? To be saved.
Saul was not saved on the road to Damascus. He was saved in Damascus after he heard what to do to be saved. He was immersed in water and his sins were washed away, Acts 22.16.
