Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you. Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
Christ died and left us an inheritance that is incorruptible and undefiled and cannot fade away. The inheritance itself is bullet-proof…. It cannot be corrupted or damaged in any way. (remember, no condemnation in Christ!) And, it is reserved in Heaven for us. Why would something be "reserved" for us if there was some question as to whether or not we would remain saved? It's "reserved" for us because we are kept not by our own obedience or morality, but by the power of God. God reserves this inheritance for us precisely because He knows we will be there. God's omniscience again.
