Labor not for the food which perishes, but for that food which endures unto everlasting life, which the Son of man shall give unto you: for on him has God the Father set his seal.
Therefore, my beloved brethren, be steadfast, unmovable, always abounding in the work of the Lord, since you know that your labor is not in vain in the Lord.
For God is not unrighteous to forget your work and labor of love, which you have showed toward his name, in that you have ministered to the saints, and do minister.
