"Therefore, my dear brothers (and sisters), stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord because you know that your labour in the Lord is not in vain." 1 Corinthians 15:58

Vain = Useless.
Vain = Having no meaning or likelihood of fulfillment.
In Vain = Without success or result.

We are not in vain.
