". . . Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour. For we are labourers together with God: ye are God's husbandry, ye are God's building. According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon. For other foundation can no man lay than that is laid, which is Jesus Christ. . . ." -- 1 Corinthians 3:8-11.
Wow, I guess you do not understand it as I have.
". . . Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: . . ." -- Matthew 28:19-20.
Jesus, as I understand this, commissioned His disciples teach their disciples, what He had taught them. And so on down the line to us. And we others after us. That was my "Baptist" training, beginning with me being won to Christ.
". . . Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work. Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest. And he that reapeth receiveth wages, and gathereth fruit unto life eternal: that both he that soweth and he that reapeth may rejoice together. And herein is that saying true, One soweth, and another reapeth. I sent you to reap that whereon ye bestowed no labour: other men laboured, and ye are entered into their labours. . . ." -- John 4:34-38.
". . . Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples. . . ." -- John 15:8.
". . . Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. . . ." -- Matthew 5:14-16.
". . . Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life. . . ." -- John 8:12.
". . . And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever. . . ." -- Daniel 12:3.
". . . The fruit of the righteous is a tree of life; and he that winneth souls is wise. . . ." -- Proverbs 11:30.
I was taught to carefully distinguish who is being addressed. This is so that we do not assume modern disciples are necessarily being talked to. We can derive when modern disciples are meant too by carefully understanding the context.
I will have to go through the scriptures you gave carefully to see who is meant as the ones addressed.
