Unless the LORD builds a house, the work of the builders is wasted. Unless the LORD protects a city, guarding it with sentries will do no good. It is useless for you to work so hard from early morning until late at night, anxiously working for food to eat; for God gives rest to his loved ones. [Psalm 127.1-2]
Most people do not really believe the words of Psalm 127.1-2. Regarding the topic of work, Christians' first thoughts usually go to these passages:
Even while we were with you, we gave you this command: “Those unwilling to work will not get to eat.” [2 Thessalonians 3.10]
But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel. [1 Timothy 5.8]
So...? What is the difference?
Here is the difference: man is to "work" out of obedience, not necessity.
Necessity is self-inspired. When man works out of necessity, that necessity drives him, not God.
Obedience is God-inspired. When a man works out of obedience, that obedience drives him, not need.
In 2 Thessalonians 3 and 1 Timothy 5 above, Paul was addressing laziness. In Psalm 127 the Psalmist (Solomon?) was addressing faithfulness. Laziness has everything to do with necessity and faithfulness has everything to do with obedience.
A lazy person ignores necessity and does nothing about it. The faithless person recognizes necessity but ignores God in doing something about it. Both have similar outcomes.
The faithful person, on the other hand, recognizes necessity and, instead of being driven by the necessity, is intentionally obedient to God. In contrast, the necessity-inspired worker is just a hard worker whose efforts are wasted.
Jesus was not unclear on the topic of being necessity-inspired or being obedient to God:
“Don’t store up treasures here on earth, where moths eat them and rust destroys them, and where thieves break in and steal. Store your treasures in heaven, where moths and rust cannot destroy, and thieves do not break in and steal. Wherever your treasure is, there the desires of your heart will also be. “Your eye is like a lamp that provides light for your body. When your eye is healthy, your whole body is filled with light. But when your eye is unhealthy, your whole body is filled with darkness. And if the light you think you have is actually darkness, how deep that darkness is! “No one can serve two masters. For you will hate one and love the other; you will be devoted to one and despise the other. You cannot serve God and be enslaved to money. “That is why I tell you not to worry about everyday life—whether you have enough food and drink, or enough clothes to wear. Isn’t life more than food, and your body more than clothing? Look at the birds. They don’t plant or harvest or store food in barns, for your heavenly Father feeds them. And aren’t you far more valuable to him than they are? Can all your worries add a single moment to your life? “And why worry about your clothing? Look at the lilies of the field and how they grow. They don’t work or make their clothing, yet Solomon in all his glory was not dressed as beautifully as they are. And if God cares so wonderfully for wildflowers that are here today and thrown into the fire tomorrow, he will certainly care for you. Why do you have so little faith? “So don’t worry about these things, saying, ‘What will we eat? What will we drink? What will we wear?’ These things dominate the thoughts of unbelievers, but your heavenly Father already knows all your needs. Seek the Kingdom of God above all else, and live righteously, and he will give you everything you need. “So don’t worry about tomorrow, for tomorrow will bring its own worries. Today’s trouble is enough for today. [Matthew 6.19-34]
If we can see it, this same theme of necessity-versus-obedience is repeated a little later in Matthew's Gospel:
“Not everyone who calls out to me, ‘Lord! Lord!’ will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter. On judgment day many will say to me, ‘Lord! Lord! We prophesied in your name and cast out demons in your name and performed many miracles in your name.’ But I will reply, ‘I never knew you. Get away from me, you who break God’s laws.’ [Matthew 7.21-23]
There is an eternal difference between doing God's will (prophesying, casting out demons, and performing miracles) out of necessity and doing it out of obedience.
A man who works hard all his life but does not bring his family into fellowship with God through Jesus Christ is a worse infidel than the man who refuses to provide for his family. Why is this so? The answer if found throughout the Bible in every direct and indirect reference to idolatry.
Idols are born of necessity. Idols are necessary when God is doubted and fear sets in. When a man works out of necessity, he has allowed himself to be driven by fear, not God's Word, making an idol of himself and his own efforts.
The truth is, every man could work much less than he does today. However, because idolatry has so subtly entrenched itself into the fabric of today's society, obedience to "self" (idolatry), rather than to God, has blinded mankind in an endless pursuit of fear-driven self-preservation and self-awareness. The result is society as we know it today. "Life" is endlessly "busy" being wastefully spent on mitigation of fear and on self-pandering in a non-ending campaign for "more."
All the while, every Bible passage and verse describing God's desire to provide for those who wholeheartedly trust Him is blasphemously ignored and even denied in the widespread Satanic belief that "God helps those who help themselves."
Jesus' words only confirm everything stated here:
If any of you wants to be my follower, you must give up your own way, take up your cross, and follow me. [Matthew 16.24 (also, Mark 8.34 & Luke 9.23)]
Father, we have believed lies instead of Your Word. The lies we have believed serve only ourselves making us disobedient to You. While religion tries to make us comfortable in our blasphemous condition of busy-ness, Your Word remains woefully unknown to most professing "Christians" today. May Your true believers come to the place of obedience to You that understands that their every necessity is Yours to meet and not theirs. May our focus be to give up our own way, take up our cross, and follow Jesus. So be it.
