In John Chapters 11-15, we see Jesus' power over death as he raises Lazarus from the dead. He then arrives in Jerusalem for the Feast of the Passover, where he teaches his disciples about his impending death and the importance of serving others. Jesus washes the feet of his disciples, predicting his betrayal and denial. He reassures his disciples of his love and promises them the Holy Spirit. He emphasizes the importance of remaining in him and the need to bear fruit through obedience. These chapters provide a profound insight into the life and teachings of Jesus Christ, highlighting the importance of love, service, humility, faith, and obedience to God's commands.
