17 So faith comes from hearing, and hearing through the word of Christ.
18 But I ask, have they not heard? Indeed they have, for
“Their voice has gone out to all the earth,
and their words to the ends of the world.”

Faith comes from hearing  – upon reading this, you may think: “Ok, I will start hearing” – and you hear, hear and hear the Word… but…
Read further …. “have they not heard”

People of Israel have heard a lot! But it does not produce faith in them. Why?

in addition to your hearing of the Word, you need to add something else… What? Let’s see what the Scripture says:

Romans 10:21
21 But of Israel he says, “All day long I have held out my hands to a disobedient and contrary people.”

Israel of old, had the Word of God and they heard the Word of God a lot, but it turns out, that it is possible to hear the Word a lot and still be  “…disobedient and contrary people…”

So add some heart qualities to your hearing.
