I Peter 1:3-5
Unbelievers have only the things of this world to hope in (such as money and fame) – things that will one day come to an end (Job 27:8). But Christians have the hope of eternal life, because the same life-giving power that raised Jesus from the dead is also at work in us (Ephesians 1:19,20). One day we will share in His glory and immortality!
Like Israel, we have been promised an inheritance (Ephesians 1:18): a permanent home in the Kingdom of God, already reserved for us (John 14:2). Israel’s inheritance (the Promised Land) was far from secure; it was often invaded by outsiders, and it became polluted by their sins. Our inheritance, on the other hand, is being kept for us in the safest possible place; it is in heaven, where we can neither lose it nor defile it! We will actually receive it only when Jesus returns, but in the meantime we can be as certain of it as if it were already ours.
Not only does God keep our inheritance safe for us; He also keeps us safe for our inheritance! Like a besieged city, we are surrounded by enemies, yet we are securely fortified and constantly guarded by the invincible power of God (Romans 8:38,39).And so my future is assured. As Paul wrote (Ephesians 1:14), our inheritance is guaranteed – underwritten by God himself. I need not torment myself with the fear that my faith may fail; God, who led me to faith in the first place, will keep me believing to the very end.
