It is very dangerous, however, to allow these hellish lies to fester and enflame your soul. Jesus showed us the way out of such despondency with this statement: “I have labored in vain…Yet surely my just reward is with the Lord, and my work with my God” (Isaiah 49:4). The Hebrew word for judgment here is “verdict,” Christ is saying, in effect, “The final verdict is with my Father. He alone passes judgment on all that I’ve done and how effective I’ve been.”
God is urging us through this verse: “Stop passing a verdict over your work for me. You have no business judging how effective you’ve been. And you have no right to call yourself a failure. You don’t yet know what kind of influence you’ve had. You simply don’t have the vision to know the blessings that are coming to you.” Indeed, we won’t know such things until we stand before him in eternity.
While the devil is lying to you, saying that all you’ve done is in vain, that you’ll never see your expectations fulfilled, God in his glory is preparing a greater blessing. He has better things in store, beyond anything you could think or ask.
We’re not to listen to the enemy’s lies any longer. Instead, we’re to rest in the Holy Spirit, believing him to fulfill the work of making us more like Christ. And we are to rise up from our despair and stand on this word: “Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord” (1 Corinthians 15:58).
