Do you mean:
Luke: 15 King James Version (KJV)
3 And he spake this parable unto them, saying,
4 What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it?
5 And when he hath found it, he layeth it on his shoulders, rejoicing.
6 And when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost.
7 I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance
Very important to note is that the above is a parable. Parables are not at all, for edification (in truth). Parables were given, only to those who were not given by God to follow Jesus and also not given by God to get the mysteries of God's kingdom of heaven from Jesus.
Also parables were given to people to take away what they have and leave them with nought. Parables were given to unworthy people. Unworthy people were the dead who were given to bury each other. The following literal and clear words from Jesus, as recorded in the Holy KJV N.T., confirms these fact about parables:
Matthew:13 KJV N.T.
10 And the disciples came, and said unto him, Why speakest thou unto them in parables?
11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
Even if we ignore the above declaration about parables, by Jesus and take the parable on face value:
The sad fact is that even after the best effort of trying to save any and all lost persons, only a few make it:
Matthew: 22 King James Version (KJV)
14 For many are called, but few are chosen.
Matthew: 7 King James Version (KJV)
14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Fact is, Jesus was not intent on saving everyone. Also Jesus did not expect his disciples to try to save everyone.
Jesus had, declared (privately to only his disciples) and practice two agendas as follows. Also Jesus left the following instruction:
Matthew: 8 King James Version (KJV)
22 But Jesus said unto him, 1.) Follow me; and 2.) let the dead bury their dead.
Those who follow Jesus must and do simply leave 'the dead' alone to bury each other (in hell, inside the earth, with Satan). This is Jesus' simple instruction to His disciples.
A billion strong Christians do bury each other inside the earth, in hell, with Satan. None follow Jesus to spirit heaven, in three days after their death.
There are just two choices.
1. One can follow Jesus to spirit heaven. That is, one can do exactly the same thing that Jesus did. This is how one follow Jesus. That is, when one dies, one must rise to spirit heaven, in three days, to be like an angel in heaven:
1 Corinthians: 15 KJV N.T.
4 And that he was buried, and that he rose again the third day according to the scriptures:
John: 14 King James Version (KJV)
2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
Mark: 12 King James Version (KJV)
25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.
In three days after death, an authentic Christian, rise and go to spirit heaven to be like an angel in heaven, in the mansion in God's house which Jesus went to prepare for those who literally and actually follow him.
2. A billion strong traditional/mainstream Christians are exercising the second option which is 'let the dead bury their dead'
A billion strong traditional/mainstream Christians are burying their dead counterparts inside the earth, in hell, with Satan for an indefinite and/or possible permanent stay. They do not literally or otherwise, follow Jesus.
In seeking Christian guidance one must accept only those deliveries which Jesus made to only his disciples in very private sessions among only them. Back then, only the disciples were given by God to follow Jesus and to get the mysteries of God's kingdom of heaven from Jesus.
All other deliveries were made to the general public. These are parables. These were given simply to appease the unruly and/or doubting masses who were not given by God to follow Jesus and also not given to get truth. Parables were given to fool-up the masses into keeping the peace.
Indeed, only the twelve disciples were given, by God, to follow Jesus:
John: 6 KJV N.T.
65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
66 From that time many of his disciples went back, and walked no more with him.
67 Then said Jesus unto the twelve, Will ye also go away?
Only the twelve disciples were given by God to get the mysteries of God's kingdom of heaven, from Jesus:
Matthew:13 KJV N.T.
10 And the disciples came, and said unto him, Why speakest thou unto them in parables?
11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
