I love this turn-of-phrase from Jaroslav Pelikan as found in "Unparalleled" on page 160.
If Christ is risen, nothing else matters. And if Christ is not risen, nothing else matters.
This is the truth that the apostle Paul shares in his first letter to the Corinthians: And if Christ is not raised, your faith is futile; you are still in your sins...But in fact Christ has been raised from the dead, the first fruits of those who have fallen asleep. (verses 17 & 20)
Because Christ is risen from the dead, you and I and all who believe can look forward to a glorious resurrection on the Last Day. And no matter how challenging or difficult life is, none of it matters because we have an eternity that awaits, an eternity spent in the presence of Jesus, our Redeemer and Savior.
And really, in the end, that's all that matters.
