Hope comes from knowing Jesus Christ promised life after death.
Jesus traveled through Israel doing miracles and telling people He was going to die and come back to life. He healed sick people, cast out demons and restored sight to the blind.
Later Jesus specifically describe how He would die and come back to life.
“Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes; and they will condemn Him to death and deliver Him to the Gentiles; and they will mock Him, and scourge Him, and spit on Him, and kill Him. And the third day He will rise again.” ~Mark 10:33-34.

She said to Him, “Yes, Lord, I believe that You are the Christ, the Son of God, who is to come into the world.”
