America will be truly great when we embrace the gospel.

For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. – Ephesians 6:12 (ESV)

America will be truly great when the church embraces her call.

The challenge is to be great in things that matter to God. Nothing is greater in God’s eyes than giving, and no vocation affords the opportunity to give more than that of a servant (10:43). Jesus’ selfless service of others fills the concept of servant with entirely new content; the posture of the servant is a visible manifestation of the reality of God’s love. Greatness in God’s economy is not reserved for the gifted and privileged; rather, it presents itself to every believer in the common and simple tasks of serving others. Indeed, the more common and humble the task, the greater the deed, for humility is the essence of him who said, “ ‘For I am among you as one who serves’ ” (Luke 22:27). Service to others is the primary way in which believers imitate and fulfill the mission of Jesus. – Edwards

Ask not what your country can do for you, but what you can do for your country. – President John F. Kennedy

America will be truly great when the church truly unites around its common mission.
