Don't work for the food which perishes, but for the food which remains to eternal life, which the Son of Man will give to you. For God the Father has sealed him.*
Therefore, my beloved brothers, be steadfast, immovable, always abounding in the Lord's work, because you know that your labor is not in vain in the Lord.
For God is not unrighteous, so as to forget your work and the labor of love which you showed toward his name, in that you served the holy ones, and still do serve them.
