So what does it mean to walk in a manner that’s “worthy of the gospel of Christ” (Phil. 1:27), and how should that look in the life of a Christ follower? In this short accessible guide, theologian Sinclair Ferguson explains the importance of living worthy of the gospel, why the principle is often forgotten, and how it’s cultivated.

In Humility, Gavin Ortlund explains that humility is not just an abstract virtue but a mark of gospel integrity, casting a vision for gospel-centered humility that is ultimately self-forgetfulness leading to joy.

Historic statements of faith—such as the Heidelberg Catechism, the Apostles’ Creed, and the Westminster Confession of Faith—have helped the Christian church articulate and adhere to God’s truth for centuries. However, many modern evangelicals reject these historic documents and the practices of catechesis, proclaiming their commitment to “no creed but the Bible.” And yet, in today’s rapidly changing culture, ancient liturgical tradition is not only biblical—it’s essential.

From a peak in church attendance in the mid-20th century, Christianity has been on a trajectory of decline in the United States.

Even lifelong Christians will find fresh encouragement by closely studying these familiar words.

In every position of power lies the potential for life-giving leadership or destructive corruption. Driven by sinful pride or opportunism, many people abuse their God-given influence, harming the ones they’re called to lead and contributing to an intense angst against authority. The answer to bad authority, however, is not no authority, but good authority—the kind that, according to Scripture, causes those under it to flourish. In this compelling guide from 9Marks, Jonathan Leeman shows that authority, done biblically, is not only good, but is essential to human flourishing.

This world has declared war on our children. Every day, on a multitude of battlefronts, Satan is deploying weapons of mass corruption against our children. Modern culture has been systematically designed with an agenda that is anti-God, anti-Christ, and anti-Scripture, intended to corrupt young and impressionable hearts and minds.
