The bible let us to know that they are some humans who are already in heaven. Elijah was taken to heaven by a strong wind and he didn't experience death. Another is Enoch, who “walked faithfully with God” and was taken by Him. The Bible also teaches that after His resurrection, Jesus opened the way for believers to have eternal life with God. These examples show that heaven is real and that God prepares a place for His faithful people.
Jesus teaches us in the new testament about some souls being with God after death.
Luke 23:43, Jesus told the repentant thief on the cross, “Truly I tell you, today you will be with me in paradise.”
This gives Christians hope that those who belong to God are not lost forever. The Bible encourages believers to live faithfully, trusting that eternal life with God awaits those who follow Him.
