Acts 22:9

"'My companions saw the light, but they did not understand the voice of him who was speaking to me.'" NIV translation

Paul continues to describe his encounter with Jesus and there were witnesses who saw the light. They heard Jesus speaking to Paul but could not understand what He was saying. Jesus was giving a specific message to Saul/Paul and his companions did not need to understand or God would have allowed them to do so. There are those that say that God/Jesus does not audibly speak to people today but there is no basis for putting such a limit on God. If He wants to tell you something, He can! (What He tells you will line up with his Word and purpose.)

Acts 22:10

"'What shall I do, Lord?' I asked. 'Get up,' the Lord said, 'and go into Damascus. There you will be told all that you have been assigned to do.'" NIV translation

When Paul came face to face with the Lord, his reaction was to fall down in worship and then it was to find out how he was to serve. Jesus told Paul that he had been assigned things to do and we may say he's Paul and God had great things planned for him which is true. But, God has also planned great things for each of us to do as Paul tells us in Ephesians 2:10.

Acts 22:11

"My companions led me by the hand into Damascus, because the brilliance of the light had blinded me." NIV translation

We might ask ourselves why God would blind Paul just as he was having a change of heart. As we shall see, God is working behind the scenes for the good of His servant. We will have some tough things happen in our walk with Christ walking through these valleys is a normal part of our growth. (see Nehemiah 3 for a look at the valley gate and its role in our walk.)
