Final answer:
Christians can share in Jesus' mission as a priest through the sacrament of baptism. This allows all believers to participate in acts of worship, service, and spreading the teachings of Jesus. They can engage in the Eucharist, show love and compassion to others, and engage in evangelism to fulfill their priestly roles.
Step-by-step explanation:
Christians can share in Jesus' mission as a priest through the sacrament of baptism. According to Christian belief, baptism consecrates all believers as priests, as stated in 1 Peter 2:9: 'Ye are a royal priesthood, a holy nation.' Therefore, every Christian has the potential to participate in Jesus' mission as a priest. This means that Christians can engage in acts of worship, prayer, service to others, and spreading the teachings of Jesus, just as a priest would.
For example, Christians can participate in the Eucharist, which is a sacrament where bread and wine are consumed in remembrance of Jesus' sacrifice. In this way, they can share in the priestly role of offering spiritual sacrifices. Christians can also serve as a channel for God's grace by showing love, mercy, forgiveness, and compassion to others, which aligns with the priestly role of intercession and mediation between God and humanity. Lastly, Christians can actively engage in evangelism, spreading the message of Jesus' love and salvation to others, which is akin to the priestly function of proclaiming God's truth.
