'Toiling' in the Bible
The blessing of the Lord brings [true] riches,And He adds no sorrow to it [for it comes as a blessing from God].
And I hated all my labour wherewith I had been toiling under the sun, because I should leave it unto the man that shall be after me.
A man who is all alone with no companion, he has no children nor siblings; yet there is no end to all his toil, and he is never satisfied with riches. He laments, "For whom am I toiling and depriving myself of pleasure?" This also is futile and a burdensome task!
This is another misfortune: Just as he came, so will he go. What did he gain from toiling for the wind?
"Come to me, all you toiling and burdened ones, and *I* will give you rest.
And he saw them toiling in rowing; for the wind was contrary unto them: and about the fourth watch of the night he cometh unto them, walking upon the sea, and would have passed by them.
Do not work for food that perishes, but for food that endures [and leads] to eternal life, which the Son of Man will give you; for God the Father has authorized Him and put His seal on Him.”
We do hard work, toiling with our own hands. When we are verbally abused, we respond with a blessing, when persecuted, we endure,
and here is the motive of our toiling and wrestling, because we have our hopes fixed on the ever-living God, who is the Saviour of all mankind, and especially of believers.
