In Acts 16:6-7, it’s unclear how the Holy Spirit stopped Paul from moving forward with his plans. It may have been through a vision, a word of prophecy, or some other circumstance. When God prompted him to go to Macedonia so the gospel could be heard there, we’re told He spoke to him through a vision (vv. 9-10). Scripture doesn’t reveal the identity of the “man of Macedonia” (v. 9), but some scholars believe it may have been Luke, who wrote the book of Acts and joined the group at this point. As believers in Jesus, when God seems to close a door, it may be that the Holy Spirit is redirecting our plans to better align with His. The Spirit of God lives inside us to guide us. Christ said of the Spirit, “He will guide you into all the truth. He will not speak on his own; he will speak only what he hears” (John 16:13; see 14:26).
