Scripture readings for this reflection can be found at Fifth Sunday of Easter | USCCB
The gospel for this Fifth Sunday of Easter from John chapter 14, verses 1-12, I think is one of the most comforting parts of Scripture. It's a gospel I read often at both wakes and funerals. Jesus is reassuring us that he will be there for us and is telling us not to be troubled. Just have faith in God and faith in Him.
Whenever I read this at a wake, I encourage all the family members to pray for the deceased and to let their hearts not be troubled. I assure the family that the deceased loved one is in the loving embrace of Jesus and is being led to a place prepared for them by the Lord. Jesus promises, "I am going to prepare a place for you." John 14:3. I encourage regular prayer for our deceased loved one to help them during their journey with Jesus towards heaven.
As we ourselves journey throughout this life here on earth, let us remember that Jesus is walking along side us. In whatever troubles we may face, let us place our troubles into the loving hands of Jesus. He will be present to us in good times and bad times. We just need to trust that He'll be with us every step of the way.
