"Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord" (1 Corinthians 15:58).
Federal Visionists love verses like this because it sounds as if Paul wants us to do something so that our “toil” in the Lord is not in vain. However, such an interpretation betrays the anti-Calvinist flavor of the Federal Vision.
God is sovereign, and we are not. God does not depend upon us in any way. In fact, it is impossible for our toil to be in vain. God has foreordained it, and so it cannot be in vain. Beware of anyone who wants to say that God depends upon us in any way. This is Arminian!
