Because each of us is unique, we are one of a kind. If we know Jesus as our personal Saviour, we are ewe-nique. We are one of his sheep. Jesus doesn’t do carbon copies, so it follows that even my grief will be different from your grief.
People who criticize us would be criticizing us over a hundred other things if they had the chance. Don’t think grief protects you. As a matter of fact, now your loved one is gone, a few people who wanted to tell you off before and didn’t, will think they are free to do so now. Don’t fight it. Instead take it to God. Tell him the truth and listen to it yourself. Do not let yourself be tied up in the barb wire others toss your way.
