Mark 1:20
Without delay he called them, and they left their father Zebedee in the boat with the hired men and followed him — the immediacy mirrors verse 18: no deliberation, no farewell, no gradual departure. The departure is complete enough to leave Zebedee still at work, mid-task, now without his sons. The family dimension of discipleship cost is present but not sentimentalized: Mark notes the departure from the father without commenting on the father's response. The double call — Simon and Andrew, then James and John — establishes the first four disciples and the inner circle that will recur throughout Mark. The kingdom's arrival creates new primary loyalties that realign every other relationship.
