Acts 16:3 this one did Paul wish to go forth with him, and having taken <FI>him<Fi> , he circumcised him, because of the Jews who are in those places, for they all knew his father--that he was a Greek.
Acts 16:4 And as they were going on through the cities, they were delivering to them the decrees to keep, that have been judged by the apostles and the elders who <FI>are<Fi> in Jerusalem,

Acts 16:6 and having gone through Phrygia and the region of Galatia, having been forbidden by the Holy Spirit to speak the word in Asia,
Acts 16:7 having gone toward Mysia, they were trying to go on toward Bithynia, and the Spirit did not suffer them,
The verse centers on "faith", "indeed", "assemblies", "established", "abounding", and "number". It is saying that the verse draws attention to "faith" and "indeed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "And as they were going on through..." into verse 6's "and having gone through Phrygia and the...", so "faith" and "indeed" belong inside that flow. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "faith" and "indeed" with trust shaped by these words, not by a vague optimism outside the passage.
