Ephesians 4:21

How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?

Now there are varieties of gifts, but the same Spirit.

In Him, you also, after listening to the word of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise,

which has come to you, just as in all the world also it is constantly bearing fruit and multiplying, just as it has been doing in you also since the day you heard and understood the grace of God in truth;

having been firmly rooted and being built up in Him, and having been established in your faith—just as you were instructed—and abounding with thanksgiving.

For the time already past is sufficient for you to have worked out the desire of the Gentiles, having pursued a course of sensuality, lusts, drunkenness, carousing, drinking parties, and abominable idolatries.
