And in Job 31, it explains why God was so pleased with Job in his former life. See what He says about him in Job 1. 31 first.
Job 31: Job, when rich, was generous:
"16 “Have I refused to help the poor,
or crushed the hopes of widows?
17 Have I been stingy with my food
and refused to share it with orphans?
18 No, from childhood I have cared for orphans like a father,
and all my life I have cared for widows.
19 Whenever I saw the homeless without clothes
and the needy with nothing to wear,
20 did they not praise me
for providing wool clothing to keep them warm?
21 “If I raised my hand against an orphan,
knowing the judges would take my side,
22 then let my shoulder be wrenched out of place!
Now, see what the Almighty Himself says about him in Job 1:
"Job and His Family
1 There was a man in the land of Uz, whose name was Job; and that man was blameless and upright, one who feared God, and turned away from evil. 2 There were born to him seven sons and three daughters. 3 He had seven thousand sheep, three thousand camels, five hundred yoke of oxen, and five hundred she-asses, and very many servants; so that this man was the greatest of all the people of the east. 4 His sons used to go and hold a feast in the house of each on his day; and they would send and invite their three sisters to eat and drink with them. 5 And when the days of the feast had run their course, Job would send and sanctify them, and he would rise early in the morning and offer burnt offerings according to the number of them all; for Job said, “It may be that my sons have sinned, and cursed God in their hearts.” Thus Job did continually.
Attack on Job’s Character
6 Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them. 7 The Lord said to Satan, “Whence have you come?” Satan answered the Lord, “From going to and fro on the earth, and from walking up and down on it.” 8 And the Lord said to Satan, “Have you considered my servant Job, that there is none like him on the earth, a blameless and upright man, who fears God and turns away from evil?” 9 Then Satan answered the Lord, “Does Job fear God for nought? 10 Hast thou not put a hedge about him and his house and all that he has, on every side? Thou hast blessed the work of his hands, and his possessions have increased in the land.
And recall that even in the Gospel, the Lord Jesus Himself says: 29“Truly I tell you,” Jesus replied, “no one who has left home or brothers or sisters or mother or father or children or fields for My sake and for the gospel 30will fail to receive a hundredfold in the present age— houses and brothers and sisters and mothers and children and fields, along with persecutions— and in the age to come, eternal life. 31But many who are first will be last, and the last will be first.” (Mark 10:29-31)
See again, how the Lord clearly says, anyone who has renounced everything for Him, as for e.g. Missionaries are called to do, will receive even many earthly blessings, along with some persecutions, and then in the age to come, Eternal Life.
