Some people don’t believe that there is a resurrection. They believe that once they have passed on from this life, there will be no other life in the future. They live, they die and memories of themselves will just fizzle away like as if they had never existed. The Sadducees (who are different from Pharisees) didn’t believe in the resurrection. There are some religions in the world today that don’t believe in the after-life. If that’s the case, what purpose is there in living this life? Why not just “live it up” while we’re here now?
We as Christians follow what Christ has taught us. He said to the other crucified criminal next to him on the other cross that “Truly, I tell you, today, you will be with me in paradise” (Lk.23:43). This was a promise he made to this criminal who repented of his sins. Jesus taught about a resurrection. There will be a resurrection of the all the dead who died believing in Jesus as Christ, the anointed One.
But why should we believe this? We believe it because Christ has indeed risen from the dead. There are historical non-biblical documents written by non-biblical writers who wrote that there was indeed a man named Jesus who was crucified on the cross and that he was accused of going against the Roman government (ex. Josephus, Pliny, Tacitus, Suetonius). Plus dozens of Christian historians from the 1-2 c. report his resurrection as a fact. And the four gospels say that he has risen from the dead. His body was not left in the tomb, but was found empty. He was witnessed by over 500 followers in the same place at the same time (read 1 Cor. 15:6).
What we have in this life is only a short brief period of chronological time. Paul wrote in Colossians 3:2-3: “Set your minds on things above, not on earthly things. For you died, and your life is now hidden with Christ in God”.
What this means is that our real life, the everlasting life that is coming is the life that we have living with Jesus. When we know that there is something greater to look forward to in the future, we will feel an amazing amount of freedom to just rest and to “be”. To just rest and “be” here on earth can free us from the worries of this life. It means we won’t have to strive or work like as if it were life and death. We can take it easy. It means that we can give up all the things that cause us to worry, and put the uncertain things into God’s hands. And God will give you an amazing peace that no human mind without of God can ever imagine. What this also means is that you will have peace in the next life, and also peace in this life.
