How do we know there is a world to come?

The Bible consistently affirms the existence of a world to come, where believers will experience life everlasting. In Luke 18:29-30, Jesus promises that those who leave everything for the kingdom of God will receive manifold blessings in this present age and eternal life in the age to come. This hope is further reinforced in Revelation 21:4, where God wipes away every tear and there is no more death or sorrow. The Apostle Paul's mention of being 'caught up into the third heaven' exemplifies the unexplainable glory of this future world that believers can only glimpse through faith. The certainty of this promise anchors the believer's hope amid the struggles of this present evil age.
