How do we know our loved ones are with Christ after they die?

The assurance that our loved ones who have passed away are with Christ hinges on their faith and relationship with Him. Paul notes in 1 Thessalonians 4:14 that if we believe that Jesus died and rose again, then God will bring with Him those who sleep in Jesus. This signifies a promise that those who have placed their faith in Christ are secure in Him even in death. It's not about their goodness or achievements, but rather their hope anchored in Christ alone. The reality of being 'asleep in Jesus' conveys the notion that they rest in His grace and presence. Thus, our focus should be not on their performance but on Christ as the object of their faith.
