John 6:16
16When evening came, his disciples went down to the sea.
Evening comes; the disciples go down to the sea as Jesus had ordered (Wesley on v. 15). They leave the mountain of his solitude and obey in the darkening hour.
Arminian interpreters hear responsible discipleship: they go because he sent them, even though Matthew says they were unwilling to leave him. Obedience here is a human act under his word, not drift.
The evening departure is of a piece with the withdrawal of v. 15. He hides from the king-making crowd; the disciples take the water-path he assigned.
The timing is his. Night and lake will become the next theater of his identity. They go down not because the story slipped, but because the Son orders both the hiding and the crossing.
