I am sorry for your loss. The Bible calls death an enemy because God created us to live forever but sin and death came about when Adam turned his back on God. Immediately God took action to undo this and soon we will see an earth that is filled with righteousness and the wicked will be no more (Psalm 37:9-11 and 29). He will also undo death in the largest resurrection ever. www.jw.org has more on how God willuse His Kingdom to do this.
