How do we know God provides for our sins?

In the sermon, it was noted that unlike other gods, who demand personal sacrifices for sins, our God supplies the sacrifice necessary for our redemption. In 1 John 4:10, it says, 'Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.' This highlights the unique nature of our God, who not only requires justice but also provides the means to satisfy that justice through Christ's sacrifice, allowing us to be considered as children of God and joint heirs with Christ. This revelation is critical in understanding God's nature as loving and merciful.
