Horatius Bonar emphasizes the contrast between God's unwavering love and humanity's persistent rejection of it, as illustrated in Jeremiah 8:6-7. He describes God's longing for repentance and connection with His people, who instead choose to ignore His love and remain in their sinful ways. Bonar highlights the various forms of rejection, including wrong words, impenitence, recklessness, and stupidity, which lead people away from recognizing God's judgments and love. Despite this, God continues to reach out, yearning for even the faintest sign of return from those who have strayed. The sermon serves as a poignant reminder of the consequences of rejecting divine love and the importance of repentance.
