Revelation 19:1-6
You Can Be Certain About Heaven

Some believe everyone will go to heaven. Some believe those who do more good than bad will go to heaven. Still others believe martyrdom is the way to unending pleasure. But the truth is that no evil can exist in God's presence. Therefore, the only way to heaven is by accepting His gift of salvation. Then that person can look forward to heaven where salvation is complete, there is no evil, and our joy will be eternal.
