“Precious in the sight of the LORD is the death of his saints” (Psalm 116:15 ESV).
The Lord doesn’t treat the lives of his children cheaply nor their experience of death. He takes great care and preparation in planning it even when death appears very sudden and unexpected. He remembers his own death on the cross—he died and rose again that Christians might live with him—and shows great mercy in their death.
It is also part of their sanctification and final way in which they are to glorify him even if they don’t die a martyr’s death. The Lord will not waste the opportunity and he does not want them to waste it either. He spoke to the apostle Peter about the death by which he would glorify his Lord and told him not to get distracted in comparing how anyone else would die. Jesus told Peter, “Just follow me.”
The call for each child of God—and those who are left behind—is to eternal glory in Christ not morbid, gothic remorse. There is a time to grieve and there is a time to remember that this is not the end. After we have suffered for a little while, Jesus himself will “restore, confirm, strengthen, and establish [us]. To him be the dominion forever and ever. Amen” (1 Peter 5:10-11 ESV).
