I am sorry about your uncle.
My neighbors young son (13 yrs old) passed away about 2 years ago. His father is a Holiness preacher, his family very involved in the church.
I attended his funeral, it was enlightening: The pastor spoke highly of Daniel. There was very little "sermon" in his words. He did talk of Daniel being in heaven, but for everyone to give him a break because he really wasn't listening to the gathering honoring him right now, becasue the angels with the swords at the gate of heaven were in the middle of chasing him down to regain their swords! He added that God really has his hands full with Daniel up there with him right now.
His friends, in his fencing class, paid tribute to him, showing us some of their skills.
It was a gathering for Daniel, about Daniel - IMHO the way it should be.
