The cross was central to Jesus' life and mission, and it should be central to the lives of his followers. Taking up one's cross means willingly sacrificing one's own interests to serve and follow Jesus each day. It involves denying oneself, prioritizing God, opening one's heart to God, and working for Jesus by living according to his teachings. True life is found not in earthly things but by completely trusting in Jesus and obeying him through faith until death.
