Helping a Loved One Find Their Way to Allah

As-salamu alaykum, I've known this brother for a few years now. He's a young man in his early 20s, born and raised Muslim, and he observes some of the basics like fasting during Ramadan, eating only halal, and avoiding alcohol. However, he doesn't regularly attend the masjid or pray, and he seems disconnected from his deen. Despite his good heart and willingness to help others, he's struggling with depression and lacks motivation. I care about him deeply and wish to see him find peace and fulfillment through his faith. I've tried to guide him gently, suggesting he start with small steps like attending Jummah prayer and opening his heart to Allah. But his response concerns me - he says he doesn't care about his own fate in the afterlife as long as his loved ones are okay. When I asked him why he still observes some Islamic practices if he doesn't care about the consequences, he admitted maybe he does care a bit. I believe he's struggling with self-sabotaging patterns and resentment, which only Allah can help him overcome if he's willing to put in the effort to pray and seek help. I want to support him, but I feel like I'm not enough motivation for him. Does anyone have advice on how I can help him find his way and encourage him to work towards a better life with Allah's guidance?
