The pregnant daughter of gospel stars The Nelons, who were killed in a plane crash, gave a heartbreaking eulogy at their celebration of life.

'Even though my heart is breaking and tears flood my eyes, I do believe that God gives us something that's worth trusting and that is him and him alone,' she said during their celebration of life on August 6. 

'In a matter of three minutes, my entire life changed. My precious family, my friends, my livelihood [were] gone with no warning. Our sweet baby boy coming in December will never know his family on this side of heaven.

'I have so many questions, so few answers.' 

The lives of the gospel group were taken when their single-engine Pilatus PC-12/47E turboprop airplane reported an 'autopilot issue during flight' and crashed in Northeast Wyoming on July 26.

Streetman said she asks God 'every day' why he took her family, but reminds herself that 'he told us in this world, we would have trouble.' 

'So I changed my why into: "Then, what now, God? How do you get the glory in the midst o this tragedy?"' 

The singer is relying on her trust in a higher power to get through this tough time, but admits she wishes God 'just let me in on' the reason. 

'I trust you, Lord, and I am thankful that you are with us,' she concluded. 

Streetman's family was traveling to Alaska to go on the Gaither Homecoming Cruise, alongside Nathan Kistler, Melodi Hodges, Larry Haynie, and Melissa Haynie.

The family filmed themselves in front of the doomed jet before taking off as they laughed among themselves just hours before the accident. 

Jason, Kelly, and Amber smiled in the post, which was captioned, 'Gaither Alaskan Cruise Travel Vlog.'

Melodi, Larry, and Melissa looked excited to board their flight in the footage.

Amber's husband Nathan, who was also on board the flight when it crashed, was not seen in the clip.

In the video, Jason said: 'Gaither Homecoming Alaskan Cruise, we are on our way. We just landed in Nebraska.'

Kelly laughed before the camera was turned around to show their pilot.

'In a matter of three minutes, my entire life changed. My precious family, my friends, my livelihood [were] gone with no warning. Our sweet baby boy coming in December will never know his family on this side of heaven,' Autumn, who is pregnant, said

Jason quipped: 'There's our wonderful pilot. This is the dude right there.'

The clip ended with the high-spirited group stating they were going to Nebraska City before traveling to Montana for a second stop. 

The Atlanta-based group was founded by Rex Nelon - Kelly's father - in 1977. Throughout the years, many people have filtered through as members. 

The group was inducted into the Gospel Music Hall of Fame in 2016 and have won many Gospel Music Association Dove Awards. 

The National Transportation Safety Board is investigating the accident.
