Finally, if Jesus Christ did not rise from the dead, he will not be seated at the right hand of the Father INTERCEDING (pleading) for us, as explained in Romans 8: 31 – 34, which reads "31 What shall we say about such wonderful things as these? If God is for us, who can ever be against us? 32 Since he did not spare even his own Son but gave him up for us all, won’t he also give us everything else? 33 Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself. 34 Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God’s right hand, pleading for us".
The scriptures says it all.
