Direct Answer
Based on the speaker’s application, “exhort one another daily” would look like Christians giving regular, direct encouragement and warning—especially around repentance—because “if it’s today, we need to be exhorting each other.” Isolation is fed by sin’s “deceitfulness” and by despair, but the transcript insists that as long as someone is alive and can hear God’s voice “today,” there is hope and they should “recover” rather than hide.
