First I have to qualify the title: I don’t know if this prophecy has not been discovered before now, but it was certainly an unanticipated blessing to me. Several years ago I was reading through the Psalms and as I was reading chapter 107 it occurred to me I had read this story before – it was basically the story of Jesus on the Sea of Galilee; two stories: calming the storm and walking on the water.
The story begins in verse 23 and I have quoted the NIV:
23 Some went out on the sea in ships;
they were merchants on the mighty waters.
24 They saw the works of the Lord,
his wonderful deeds in the deep.
25 For he spoke and stirred up a tempest
that lifted high the waves.
26 They mounted up to the heavens and went down to the depths;
in their peril their courage melted away.
27 They reeled and staggered like drunkards;
they were at their wits’ end.
28 Then they cried out to the Lord in their trouble,
and he brought them out of their distress.
29 He stilled the storm to a whisper;
the waves of the sea were hushed.
30 They were glad when it grew calm,
and he guided them to their desired haven.
31 Let them give thanks to the Lord for his unfailing love
and his wonderful deeds for mankind.
32 Let them exalt him in the assembly of the people
and praise him in the council of the elders.
The prophecy, if it is in fact a prophecy, is fulfilled in the New Testament in John 6:16-21 –
16 When evening came, his disciples went down to the lake, 17 where they got into a boat and set off across the lake for Capernaum. By now it was dark, and Jesus had not yet joined them. 18 A strong wind was blowing and the waters grew rough. 19 When they had rowed about three or four miles, they saw Jesus approaching the boat, walking on the water; and they were frightened. 20 But he said to them, “It is I; don’t be afraid.”21 Then they were willing to take him into the boat, and immediately the boat reached the shore where they were heading.
and in Luke 8:22-25 –
22 One day Jesus said to his disciples, “Let us go over to the other side of the lake.” So they got into a boat and set out. 23 As they sailed, he fell asleep. A squall came down on the lake, so that the boat was being swamped, and they were in great danger.
24 The disciples went and woke him, saying, “Master, Master, we’re going to drown!”
He got up and rebuked the wind and the raging waters; the storm subsided, and all was calm. 25 “Where is your faith?” he asked his disciples.
In fear and amazement they asked one another, “Who is this? He commands even the winds and the water, and they obey him.”
The reference in the OT passage to “merchants” could of course be applied to the fishermen as this was their livelihood.
Is it a prophecy fulfilled in the NT by Jesus? You will have to decide for yourself – I am convinced it is. And it was certainly a new personal discovery for myself even if others have discovered it for themselves. It just proves to me that you can read the Bible for fifty years and never exhaust its secrets.
