The apostle Paul wrote these encouraging words to the church at Rome...
(Romans 8:34-35) Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?"
"At the Saviour's resurrection a few graves were opened, but at His second coming all the precious dead shall hear His voice, and shall come forth to glorious, immortal life. The same power that raised Christ from the dead will raise His church, and glorify it with Him, above all principalities, above all powers, above every name that is named, not only in this world, but also in the world to come."
The promise of life eternal by Jesus, along with the proof already provided, is what we can base our grandest hopes.
In the Gospel of John Chapter 11, Verses 24,26 we read this guaranteed statement of Jesus. 24 Martha saith unto him, I know that he shall rise again in the resurrection at the last day. 25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: 26 And whosoever liveth and believeth in me shall never die.
