Take note of the last lines of 1 Corinthians 15. In this chapter, Paul has gone on and on about the resurrection of Jesus and how our faith hangs upon that fact. Because Jesus lives we are assured a blessed future. Our weak and corruptible bodies will be transformed in a flash. Because Jesus lives, so will we. But that future tense doesn’t mean the Christian life is gazing off on the horizon. We do look ahead and can sing a triumphant song, as Paul does, because in Christ we have the victory. But in Christ we still live our lives in the present. Paul writes:
Therefore, my beloved brothers, be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain.
He says “therefore” showing that this line is building upon the truth of the resurrection and our future hope. Because we will be made new in Christ, we now work for the Lord in all we do. The Christian hope does not remove our responsibilities for this life. Rather it should give us all the more reason to work for Christ’s kingdom today, knowing that such labor will never be in vain.
