The parents of slain singer Christina Grimmie are in deep mourning over her death but said that they are looking to Jesus Christ for strength.

During the public memorial service for the singer in Medford, New Jersey on June 17, her mom Tina said, "I don't have too much to say.

"To anybody who says that I'm strong, I want you to know that I'm the weakest person here, and I declare my dependence on Jesus Christ because I don't have anything else. It's just so much," she said, according to Us Weekly.

Her dad, Bud, hugged his wife and told the audience, "I don't like being in front of crowds, but this crowd has blessed me beyond words.

"I want to share what I've shared with several people here and that's that there's this gigantic hole in my heart that I know is never going to go away.  

He added, "God showed me that he's way bigger than that hole."

Grimmie was shot on June 11 by Kevin James Loibl as she was signing autographs in Orlando, Florida. She later died in hospital.

During the memorial service, her father added, "The three things that keep me walking upright, otherwise I would just be a crumpled up mess in the corner, are that I know I'm going to see her again ... she's way better off now, she's more alive now than she's ever been, she's not going to be hurt anymore, and thirdly, and this is where I'm wrestling, is that God's plan is better than my plan," he said.

Grimmie's older brother Marcus, who tackled his sister's killer during the shooting, also spoke briefly.

"I don't have anything to say, I don't have words still and it's a good and bad thing. All I'm going to say is thank God for the mark that she left on this world," he said.

Christina placed third on "The Voice" Season 6 and worked with coach Adam Levine.

On his Facebook account, Marcus said Levine personally called his mother and said he would pay for the funeral and plane ticket.

"Words cannot express ... literally I have no words," Marcus wrote.
