What does 'taking up your cross' mean?

In Mark 10, Jesus instructs the rich young ruler to sell all he has, take up the cross, and follow Him. This call to discipleship signifies total surrender and the willingness to forsake all, including material wealth and personal ambitions, for the sake of Christ. It reflects the principle that true followers of Christ must prioritize their faith above earthly concerns and comforts. This is echoed in Mark 8:34, where Jesus states that anyone who wishes to follow Him must deny themselves and take up their cross daily, embodying the cost of discipleship required in a believer's life.
