Miracles and signs
The Bible often speaks of signs and miracles as things that convinced people of the Lord's leading. "Signs" convince people to believe intellectually, and "miracles" convince people to believe emotionally. For instance, it was a "sign" for the shepherds that they would find the newborn Jesus wrapped in swaddling clothes, lying in a manger. This was not something that defied explanation; there is nothing impossible about a baby being laid in a manger. On the other hand miracles such as the Nile turning into blood, the Red Sea parting or water being made wine were apparently impossible, striking awe and fear in the hearts of observers and thus compelling the emotions. Both signs and miracles, however, are external events that could only force people into compliance out of fear and awe, which is an external form of worship that has little to do with eternal life. The Lord used them in Biblical times because the people of that time were external in nature, and the Lord had to force them into forms of worship to preserve spiritual ideas and to allow for the Bible to be written. Through His advent and His teachings He opened the possibility that we could understand His spiritual meanings, which would allow us to believe and live internally, not just externally.
John 21:2-13
2
Simon Peter, Thomas called Didymus, Nathanael of Cana in Galilee, and the sons of Zebedee, and two others of his disciples were together.
3
Simon Peter said to them, "I'm going fishing." They told him, "We are also coming with you." They immediately went out, and entered into the boat. That night, they caught nothing.
4
But when day had already come, Jesus stood on the beach, yet the disciples didn't know that it was Jesus.
5
Jesus therefore said to them, "Children, have you anything to eat?" They answered him, "No."
6
He said to them, "Cast the net on the right side of the boat, and you will find some." They Cast it therefore, and now they weren't able to draw it in for the multitude of fish.
7
That disciple therefore whom Jesus loved said to Peter, "It's the Lord!" So when Simon Peter heard that it was the Lord, he wrapped his coat around him (for he was naked), and threw himself into the sea.
8
But the other disciples came in the little boat (for they were not far from the land, but about two hundred cubits away), dragging the net full of fish.
9
So when they got out on the land, they saw a fire of coals there, and fish laid on it, and bread.
10
Jesus said to them, "Bring some of the fish which you have just caught."
11
Simon Peter went up, and drew the net to land, full of great fish, one hundred fifty-three; and even though there were so many, the net wasn't torn.
12
Jesus said to them, "Come and eat breakfast." None of the disciples dared inquire of him, "Who are you?" knowing that it was the Lord.
13
Then Jesus came and took the bread, gave it to them, and the fish likewise.
