"…each one will receive his own reward according to his own labor. " so saith Paul.

I have written about this many times.  Here however, we have Paul saying the same thing I've been saying and it is all in one place. 

To recap, we are saved by grace so that none may boast but our rewards in Heaven are based on the amount of service we provide to God.  So not everybody gets the same reward in Heaven which shoots the claims that God is a Socialist in the foot.

1 Corinthians 3:5-15(NKJV)

Who then is Paul, and who is Apollos, but ministers through whom you believed, as the Lord gave to each one? 

I planted, Apollos watered, but God gave the increase. 

So then neither he who plants is anything, nor he who waters, but God who gives the increase. 

Now he who plants and he who waters are one, and each one will receive his own reward according to his own labor.

For we are God’s fellow workers; you are God’s field, you are God’s building. 

According to the grace of God which was given to me, as a wise master builder I have laid the foundation, and another builds on it. But let each one take heed how he builds on it. 

For no other foundation can anyone lay than that which is laid, which is Jesus Christ. 

Now if anyone builds on this foundation with gold, silver, precious stones, wood, hay, straw, 

each one’s work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one’s work, of what sort it is. 

If anyone’s work which he has built on it endures, he will receive a reward. 

If anyone’s work is burned, he will suffer loss; but he himself will be saved, yet so as through fire.
