The second reference to Christ is also subtle:
 

“He was asleep in a short time and he dreamed of Africa when he was a boy and the long golden beaches and the white beaches, so white they hurt your eyes, and the high capes and the great brown mountains. He lived along that coast now every night and in his dreams he heard the surf roar and saw the native boats come riding through it. He smelled the tar and oakum of the deck as he slept and he smelled the smell of Africa that the land breeze brought at morning.

Usually when he smelled the land breeze he woke up and dressed to go and wake the boy. But tonight the smell of the land breeze came very early and he knew it was too early in his dream and went on dreaming to see the white peaks of the islands rising from the sea and then he dreamed of the different harbors and roadsteads of the Canary Islands.

He no longer dreamed of storms, nor of women, nor of great occurrences, nor of great fish, nor fights, nor contests of strength, nor of his wife. He only dreamed of places now and of the lions on the beach. They played like young cats in the dusk and he loved them as he loved the boy. He never dreamed about the boy. He simply woke, looked out the open door at the moon and unrolled his trousers and put them on. He urinated outside the shack and then went up the road to wake the boy. He was shivering with the morning cold. But he knew he would shiver himself warm and that soon he would be rowing.” 
– p. 24-25

“I live by faith in the Son of God, who loved me and gave himself for me.”
– Galatians 2:20

As I said, these first 2 references are subtle and debatable. But the next ones are not so easily dismissed.
