Just keep working, because...who knows?

Scripture:
Sow your seed in the morning, and at evening let your hands not be idle, for you do not know which will succeed, whether this or that, or whether both will do equally well.
Ecclesiastes 11:6 (NIV)

Application:
When we faithfully execute our mission, we usually will not see the fruits of our labor right away. Some of us have missions which do not have any visible signs of success. Many of us may every pass away without knowing whether our toil and sacrifice had any effect. 
But we must have faith in Jesus. 
We must have faith that our work is not in vain. After a good day of honest work, we can rest assured that the Lord blesses our efforts and we will be rewarded many times over. Just keep working. 

Prayer:
An honest day's work is what we want to give to You, Lord. Please clear the obstacles that will try to impede our service. Amen.
