What does the Bible say about our inheritance in heaven?

1 Peter 1:4 states that our inheritance is 'incorruptible and undefiled' and that it 'fadeth not away.' This emphasizes the eternal and untainted nature of what God has prepared for His people. Unlike earthly inheritances that can decay or become corrupted, this heavenly inheritance is secure and everlasting. It is described as being reserved for believers, affirming that it is intended for those who have faith in Christ, representing the assurance that God’s promises are immutable and that His people will inherit this eternal blessing.
