What does the Bible say about our inheritance as Christians?

According to 1 Peter 1:4, believers in Christ have an inheritance that is incorruptible and undefiled, reserved in heaven for them. This inheritance does not fade away and is characterized by its permanence and purity, unlike earthly possessions that are subject to decay. The nature of this inheritance is spiritual rather than material, encompassing knowledge, holiness, and the promise of eternal life. It is a profound comfort to believers, affirming that despite earthly sufferings or trials, they have a secure hope in what God has promised through Christ.
