John Calvin Commentary 1 Thessalonians 1:10

"and to wait for his Son from heaven, whom he raised from the dead, [even] Jesus, who delivereth us from the wrath to come." — 1 Thessalonians 1:10 (ASV)

Whom he raised up. He makes mention here of Christ’s resurrection, on which the hope of our resurrection is founded, for death everywhere besets us. Therefore, unless we learn to look to Christ, our minds will falter at every turn. For this same reason, he admonishes them that Christ is to be waited for from heaven, because we will find nothing in the world to sustain us, while there are innumerable trials to overwhelm us.

Another point must be noted; for as Christ rose for this purpose—that he might ultimately make us all, as his members, partakers of the same glory with himself—Paul intimates that his resurrection would be vain, unless he again appeared as their Redeemer, and extended to the whole body of the Church the fruit and effect of that power which he manifested in himself.
