How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard?
And how can they hear without someone preaching to them?

Romans 10:14

The outward testimony of the life of a believer in the Lord Jesus – demonstrating the truth of their faith by how they live – is a necessary and effective means of witnessing. At some point though, the unsaved need to actually hear the word of the Lord on the matter of faith and salvation. Faith comes through hearing and hearing, by the word of Christ (Rom.10:17).
