1 Corinthians Chapter 3

¹And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.
 ²I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.
 ³For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
 ⁴For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal? 

     Here Paul is making a point of the spiritual condition that the Corinthians are in. They have to be fed milk because there fighting amongst themselves indicates that they are still carnal. Carnal means fleshly desire.
 
 ⁵Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man?
 ⁶I have planted, Apollos watered; but God gave the increase.
 ⁷So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. 

Them fighting over Paul or Apollos for credit is pointless as it is GOD that gives the increase.
 
 ⁸Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.
 ⁹For we are labourers together with God: ye are God's husbandry, ye are God's building.
 ¹⁰According 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.
 ¹¹For other foundation can no man lay than that is laid, which is Jesus Christ.
 ¹²Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
 ¹³Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
 ¹⁴If any man's work abide which he hath built thereupon, he shall receive a reward.
 ¹⁵If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. 

All labor should be built upon the foundation of Christ and the type of work that is built will determine reward. A point that is sometimes forgotten that is made here is that only Christ can give the reward not man , and not a church. In verse 15 we find out that a man's work can suffer loss but he will still be save , yet by the fire which in modern terms would be : "by the skin of your teeth".
 
 ¹⁶Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
 ¹⁷If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are. 

If you put two and two together here this passage is talking about defiling your body by living by your carnal desires and those works God will destroy because your body is the temple of God. As we read more in 1 Corinthians you will notice ways that this Church defiled the temple of God which is there bodies.
 
 ¹⁸Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.
 ¹⁹For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
 ²⁰And again, The Lord knoweth the thoughts of the wise, that they are vain. 

Glorying in man's wisdom is pointless . A point that has always helped me in my relationship with the Lord is knowing that the world's wisdom is foolishness with God . How many have us been called foolish for believing in the gospel , the world's wisdom and God's wisdom are incapable. The other point made right here is that worldly wisdom is really vainity (verse 20)
 
 ²¹Therefore let no man glory in men. For all things are your's;
 ²²Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are your's;
 ²³And ye are Christ's; and Christ is God's.

The basic , essential theme of this chapter glorying in men is worthless , all glory goes to Christ  and he is God's. I skimmed over the middle of the chapter but right now I want to reiterate we all will be tried for our works and they could stand or they could burn up it says we will still be saved but none of us Christians should want to spend eternity poor. If all our rewards are burned up we will in one sense be poor. God bless you.
