How do we know that God has the authority to protect His people?

God's authority is clearly defined in Zechariah 12:1, where He is described as the one who stretched out the heavens and laid the foundations of the earth. This declaration of His creative power serves as the bedrock for His authority. Throughout Scripture, we see numerous assurances that God is in complete control of the cosmos and is active in the affairs of humanity, especially in protecting His people. His fulfillment of promises and His sovereignty over nature, history, and salvation confirm that He possesses the necessary authority to safeguard His church against all adversities and trials, ensuring that not one of His chosen will be lost.
