It is a joy to be included and wanted. Jesus wants us to be with Him. We can be comforted that this life isn’t all there is. We have sorrow in bereavement, but it is without the hopelessness. When Christ returns the dead in Christ will rise first and receive their glorified bodies.
It’s a mistake to think that Christians don’t have genuine sorrow when death and loss come. Being a Christian does not spare you from the hurts of life. Having Jesus in our sorrow sanctifies the grief so that the bitterness isn’t there.
