Hundred
It's a landmark for a young child to count to 100; it sort of covers all the "ordinary" numbers. One hundred is obviously significant for other groupings: 100 cents is a dollar; 100 yards is a touchdown; 100 years is a century, and the landmark for a very long life. It makes sense, then, that in the Bible, 100 represents fullness or a state of completion, or in some instances simply "much." For instance, people marvel that Abraham had Isaac when he was 100 years old; the number represents the point at which the Lord, when growing up as Jesus, united the human elements of himself with the divine elements and in a sense became "complete.
Luke 16:22-31
22
It happened that the beggar died, and that he was carried away by the angels to Abraham's bosom. The rich man also died, and was buried.
23
In Hades, he lifted up his eyes, being in torment, and saw Abraham far off, and Lazarus at his bosom.
24
He cried and said, 'Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue! For I am in anguish in this flame.'
25
"But Abraham said, 'Son, remember that you, in your lifetime, received your good things, and Lazarus, in the same way, bad things. But now here he is comforted and you are in anguish.
26
Besides all this, between us and you there is a great gulf fixed, that those who want to pass from here to you are not able, and that none may cross over from there to us.'
27
"He said, 'I ask you therefore, father, that you would send him to my father's house;
28
for I have five brothers, that he may testify to them, so they won't also come into this place of torment.'
29
"But Abraham said to him, 'They have Moses and the prophets. Let them listen to them.'
30
"He said, 'No, father Abraham, but if one goes to them from the dead, they will repent.'
31
"He said to him, 'If they don't listen to Moses and the prophets, neither will they be persuaded if one rises from the dead.'"
