God puts us in various places to serve Him, and the secret of accomplishing the most is to recognize our place as designated from Him and our service in it as pleasing to Him. Even in the great factory or the complex machine there is a place for the smallest screw and rivet as well as the great driving wheel and piston. So God has His "small parts" whose business is simply to stay where He puts them and to believe that He wants them there and is making the most of their lives in the little spaces that they fill for Him.
There is something all can do, Though you're neither wise nor strong; You can be a helper true, You can stand when friends are few.
1 Thessalonians 4:1
Finally, dear brothers and sisters, we urge you in the name of the Lord Jesus to live in a way that pleases God, as we have taught you. You live this way already, and we encourage you to do so even more.
