How do we know that God's mercies are essential for our service?

In his appeal in Romans 12:1, Paul emphasizes that our ability to present our bodies as living sacrifices relies heavily on the mercies of God. This dependence acknowledges our inability to fulfill God's commands through our strength alone. It is through God's mercies—His grace and compassion towards us—that we find the motivation and enabling power to serve Him faithfully. Recognizing our need for His mercy leads to a humble posture, allowing us to live in ways that honor Him and reflect His character in our daily interactions and responsibilities.
