Why is the bodily resurrection of Christ so important? Not only will we live with Him because He rose but we see that Christ conquered death by His own death AND resurrection. The fact that Christ rose from the dead means two things: Death has no power over Him, and He has demonstrated His power over death! Because of sin, death came into the world and everyone experiences this according to Romans 5:12. Death would be the hideous end to life if Christ never rose! People without the Lord are people without hope. What kind of an "end" to life do they have to look forward to? Only a miserable and eternal death separated from God!
Knowing Christ rose from the dead means He has given us victory over death as well, 2 Corinthians 15:55-57. Remember, when you received Christ you were baptized (immersed) into His work on the cross - His death, burial, and resurrection. Your "end of life" experience is to enter into eternal life forever united with God! That couldn't happen if Christ did not rise from the dead.
