to an incorruptible and undefiled inheritance that doesn't fade away, reserved in heaven for you,
Reserved in heaven for you ...  It is reserved for them who shall be entitled to it; it will be there ready for them; none other shall preempt it or take it away from them.  Notice the emphasis upon heaven.  Peter had heard the Master say, "Great is your reward in heaven"  (Matthew 5:10-12). The essential "other-worldliness" of the Christian faith shines in a passage like this, where the pilgrims, sojourners, and citizens of heaven are called to contemplate the eternal nature of their ultimate reward, the glory of the everlasting inheritance.
