Some people seek to comfort themselves with the idea that "God needed another angel," so he took their loved one. Others think they can talk with their departed loved one and that he or she is looking down from above upon them. There is no biblical basis for these sentiments.
Rather than thinking of Jesus' Second Coming as an add-on to our faith, what about making it part of our hope? In other words, the fullness of our redemption will come on the Great Last Day when Jesus returns in glory and we will be with him forever. This is not an add-on to our faith. It is our true Christian hope and source of purest and perfect comfort.
