The central message of this sermon is that true love is not about individual feelings or accomplishments, but rather a quality that reflects the character of God. The passage from 1 Corinthians 13 describes what love is (patient, kind, etc.) and what it is not (boasting, envy, etc.), highlighting the distinction between jealousy (desiring something rightfully yours) and envy (desiring something not rightfully yours). Through various examples and scripture references, the teacher shows how love's patient and long-suffering nature is reflected in both human relationships and God's relationship with humanity. Ultimately, the sermon encourages listeners to recognize and embody this kind of selfless, other-focused love in their own lives.
