In the sermon "A Fleshly Heart," we were confronted with humanity's relentless pull towards sin, starting with Adam and Eve's catastrophic temptation. The message demands that we recognize and viciously address our sinful nature, live fiercely according to the Spirit, and take drastic measures to eradicate sin. We were challenged to scrutinize our heart, fight for righteousness, and strive for a heart that is passionately responsive to God and His ways.
