Romans 10:14 rhetorically says we must speak God's Word for another to hear and thus receive it.
Similarly, Jeremiah 23:29 says, ' "Does not my word burn like fire?" says the Lord. "Is it not like a mighty hammer that smashes a rock to pieces?" ' So then, in addition to prayer, verbally profess God's Word to others so that they might turn to Him.
