"But I said, 'I have labored to no purpose; I have spent my strength in vain and for nothing. Yet what is due me is in the Lord's hand, and my reward is with my God.'" Isaiah 49:4
Have you ever felt like you're spending your life using your talent for nothing? Life is often spent doing mundane activities that seem to have little eternal purpose.
The great prophet Isaiah was struggling with his own purpose. He knew he was chosen to be a voice for God, yet life became purposeless for Isaiah. We all go through periods when our purpose seems to be clouded with the mundane. We see little meaning in life. On the other hand, Isaiah didn't stay in this place. We read in this passage that he knew the truth of his existence. He could look past his present circumstance and know that his real reward and purpose would be revealed in eternity. He knew that God was just and fair, so he placed his faith on this truth.
When life appears to lack meaning and purpose, remember that if you devote your life to the purposes He has for you, the fruits of your labor will be manifested in due time. "The one who calls you is faithful and He will do it" (1 Thess. 5:24).
