The answer is: Their cross

Mark 8:34

When Jesus mentions "take up their cross" in Mark 8:34, it's a powerful invitation to embrace both the joys and challenges of discipleship. The cross is emblematic of sacrifice and commitment; it’s about serving others and following a path that might not always align with societal expectations.

This was particularly provocative given that in ancient Rome, the cross symbolized the brutal execution reserved for rebels and criminals. So, Jesus wasn't just inviting his followers for a comfortable stroll; he was calling them to enter a radical lifestyle choice that might lead to hardships.

Interestingly, the act of carrying one's cross involves public declaration. In Roman times, condemned individuals would carry their crosses through the streets, a humbling and often humiliating act. Similarly, for believers, embracing their own crosses often means stepping outside settled norms, announcing their values unapologetically, and enduring potential ostracism in a culture that might not take kindly to such ideas.

Moreover, many early Christian martyrs used the symbolism of the cross as a source of hope and strength, feeling that by sharing in Christ's suffering, they were also sharing in his glory. This principle is echoed throughout biblical history; think of the patience and faith exemplified by Job or the undying loyalty of Ruth.

So, when one hears “pick up your cross," remember it’s an active, sometimes uphill journey filled with purpose and deep-rooted meaning within the tapestry of biblical narratives, calling for a daily submission to a life that genuinely serves higher ideals.
