Why is the doctrine of sinfulness important for Christians?

The doctrine of sinfulness is foundational for Christians because it reveals our true condition before a holy God. Zechariah 7 illustrates the reality that all people, even those who appear religious, are sinners in need of repentance. Recognizing our depravity helps us grasp the necessity of salvation through Christ. It points us to the truth that we cannot rely on our actions or righteousness to stand before God, reiterating that we need a Savior. This understanding leads to heartfelt gratitude for God’s mercy and grace, encouraging believers to rely completely on Christ's sacrifice for their righteousness.
