Why is grace essential for serving God?

Grace is the unmerited favor of God which is necessary for any genuine service to Him. We see in Scripture that without God's grace, mankind remains dead in sin and incapable of serving Him (Ephesians 2:1). Grace not only calls the sinner but also empowers him to respond to the gospel. As believers, it is by grace that we are able to see our need for Christ and rely on His righteousness instead of our own. Therefore, any service rendered to God flows from an understanding and acceptance of His grace, allowing us to fulfill our role as His servants joyfully and sincerely.
