How do we know the Gospel is for sinners?

The Gospel is fundamentally good news for sinners. In Zechariah 13:1, God promises that a fountain will be opened for the house of David and the inhabitants of Jerusalem, highlighting that the offer of grace extends to those who recognize their sinfulness. The New Testament reinforces this, emphasizing that Christ came to save those who are lost and calls sinners to repentance. It is through recognizing our sin and need for salvation that we appreciate the depth of God's mercy in providing a way of cleansing through Christ's sacrificial death. This underscores the character of God's grace, which is freely given to the worst of sinners, demonstrating His love and desire for restoration.
