God certainly does reward all work:
'For God will bring every work into judgment,
Including every secret thing, whether good or evil.'
Also it is written
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Now if we're not walking in the works God's prepared for us, we could still be working extremely hard (in fact, we'll have to work MUCH harder as we'll be resisting The Holy Spirit, which is always painful, so don't allow the devil to condemn you. The work of God is just to believe (trust Him) as Xino mentioned. Think of prophesy. This is where God speaks through a person. He physically controls their mouth. It's the Holy Spirit who gives them the utterance, as with praying in tongues. Yeshua's yoke is easy and His burden is light. God is sending people to preach the gospel to every creature. How does this happen? Well, we're told in Romans 8.14 that as many as are are led by The Spirit of God, these are sons of God, so that means The Holy Spirit is leading people to preach the gospel to every creature. Now that means following His specific guidance:
Now when they had gone through Phrygia and the region of Galatia, they were forbidden by the Holy Spirit to preach the word in Asia.
It's clear that the devil is hindering people from doing God's will. One of his main objectives (if not the main objective) is surely to hinder the preaching of the gospel, since when the gospel has been preached to all nations for a witness, the end shall come. I submit to you that many have fallen into the devil's snare by thinking they need to be doing a particular job in a particular place, but ignoring God's instruction to preach the gospel to every creature and as a result have brought the wrath of God on themselves. Paul said this on the subject:
For if I preach the gospel, I have nothing to boast of, for necessity is laid upon me; yes, woe is me if I do not preach the gospel!
(1 Cor 9.16)
Paul did say that people should work, but I'm not convinced this is true for everyone, as he also said that God has commanded that those who preach the gospel shall live by the gospel. Even if it is true that everyone should work, I want to reiterate that we need to be walking in the works God has prepared for us and if we're not we will struggle to do whatever work we're doing instead. In this case, an obvious device of the devil is to accuse the person in question of laziness, so as to try to get them to carry on doing this work God doesn't want them to be doing. This is called a dead work:
Therefore, leaving the discussion of the elementary principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God, of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment.
Then I heard a loud voice saying in heaven, “Now salvation, and strength, and the kingdom of our God, and the power of His Christ have come, for the accuser of our brethren, who accused them before our God day and night, has been cast down.
Above all though, for anyone who has repented and been baptised (full immersion in water) in the Name of Yeshua and received The Holy Spirit, it will be painfully obvious if they dare to resist Him:
And you have forgotten the exhortation which speaks to you as to sons:
“My son, do not despise the chastening of the Lord,
Nor be discouraged when you are rebuked by Him;
For whom the Lord loves He chastens,
And scourges every son whom He receives.”
If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. Furthermore, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness. Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it.
Proverbs 14.23, quoted earlier:
In all labor there is profit,
But idle chatter leads only to poverty.
This is true, but we must remember for the third time the passages in The New Testament (one of which I quoted above) which make it clear that we need to be doing only those works which God has called us to. There is certainly profit in labouring for God. Not all labour is for God though: sometimes people have done work for which there is financial reward but that labour results in damnation, which is a more horrific reward than imaginable.
Now godliness with contentment is great gain. For we brought nothing into this world, and it is certain we can carry nothing out. And having food and clothing, with these we shall be content. But those who desire to be rich fall into temptation and a snare, and into many foolish and harmful lusts which drown men in destruction and perdition. For the love of money is a root of all kinds of evil, for which some have strayed from the faith in their greediness, and pierced themselves through with many sorrows.
It's His will which must be done and we must find out what that is. Yahshua said that The Holy Spirit will teach those who've received Him in all things, so He'll teach us what God's will for our lives is.
I must admit your question has been similar to one I've asked many times. Sometimes the answers, whilst simple, are misunderstood by some. Think of the parable in which Lazarus (a beggar) makes it to heaven whilst the rich man goes to hell. This flies completely in the face of the misguided view of many who seem to value money so highly they'll trample on the next man (and do anything else to get it), when God's command is that we love our neighbours as oursleves (which is only possible by receiving the righteousness available in Yahshua, which in turn is only possible by repenting and being baptised (full immersion in water as an adult) into Him, at which point we can receive the promise of God to pour out His Spirit on all flesh. Those who do this are guided into all the truth by His Spirit (as long as they don't resist Him, which leads to being stiff necked) and can become the righteousness of God in Him.
The story of the rich man and Lazarus also flies in the face of the assertion that all beggars are lazy sinners, whilst those on the way to heaven all have plenty of money beacuse they are working. Paul did work, but he also described himself as poorly clothed and homeless and we're warned by James not to look down on the poor or judge them less worthy than the rich or people with enough money not to be classified poor.
