I am sorry for the death of your dear Mr. Lewis.  Too young, too soon. The God of heavens shares your loss also (Ezekiel 18:32).  He plans to eradicate all sources of suffering, including death (Revelation 21:3-5).  He promises to return him back younger and in perfect health (Hosea 13:14; Job 33:25).  Jesus even taught us to pray for that marvelous time at Matthew 6:9-10.  I have found the free website, JW.ORG, most helpful for more verses of comfort and hope. It is my sincere wish that it will help you as well.  May the peace of God be with all of you. My heartfelt condolences.  Psalm 37:11, 29.
