Our labor is not in vain, if we do it in the Lord  -  1 Corinthians 15:58

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

In view of the certainty of Christ’s resurrection and the fact that faith in Him is not in vain, we can be steadfast, immovable, always abounding in the Lord’s work, knowing that our labor is not worthless. The truth of the resurrection changes everything, as it provides hope and steadfastness and enables us to go on in the face of overwhelming and difficult circumstances.
