I offer my heartfelt condolences to your family. 1 Corinthians 15:25, 26 says "For he [Jesus] must rule as king until God has put all enemies under his feet. And the last enemy, death, is to be brought to nothing". At Revelation 21:4 it says regarding Jehovah, "And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away." Finally, take courage in the hope of the resurrection promised at Acts 24:15 "And I have hope toward God, which hope these men also look forward to, that there is going to be a resurrection of both the righteous and the unrighteous."
