“Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming.” - 1 Peter 1:13
Peter was named by Christ as the rock of the Church This letter may not have been written by him, but was written in his name, probably a decade after the fall of Jerusalem. Peter would have been dead, but still remembered in Rome where this letter probably originated. Christians were being persecuted on the pretext of amoral behaviour.
Jesus came, and gave signs that He was God. Instead of ruling the world, Christ submitted to it and has beaten Satan through the cross. Satan no longer has authority in the world, but still whispers promises and misleads people. When Christ comes again, he will forever deal with Satan.
It is not the lot of the Christian to fight Satan, but resist him. If we fight Satan, we lose sight of our true lord, and end up dancing to Satan’s tune. We don’t know when Christ will come again. But we know he will. We must not get drunk on our zeal to do right.
