As Christians we are always told to remember how brief life is. How everything we have and everything we know on earth is passing away. The inevitability of death should continually be in our minds so we don’t become self-confident, and so we don’t forget to live our lives for Christ. This is good. We constantly need to remember our fatality.
However I think people who dwell on death can make the mistake of forgetting to also dwell on life.
1 Corinthians 15:32 “If from human motives I fought with wild beasts at Ephesus, what does it profit me? If the dead are not raised, ‘Let us eat and drink, for tomorrow we die'”
If all we make our focus on is death, then all we have is the sting of life. If all we remember is Christ’s death we are missing the most vital part of the gospel–His resurrection. He’s not dead anymore, He’s alive. We may die, but like Christ, we will live.
If death was the end, all our work for the Kingdom would be in vain. We wouldn’t be justified. Jesus wouldn’t be God. The whole message of salvation would be a lie. But because Christ rose, we will also appear with Him in glory. He’s conquered death.
Because He lives, we can die to sin and live for Him… and one day sin will die.
1 Corinthians 15:54-57 “But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, ‘Death is swallowed up in victory. O death, where is your victory? O death, where is your sting?’ The sting of death is sin, and the power of sin is the law; but thanks be to God, who gives us the victory through our Lord Jesus Christ.”
