Catholic influencer Paul Kim's wife, Maggie Kim, is speaking out following the death of her 5-year-old son, Micah. "Micah, I miss you. There is a deep, aching hole in my heart," Maggie wrote via Instagram on Friday, January 2. "Even though our home is filled with people, it's too quiet without you. I keep thinking I'll look outside and see you laughing on the swings. Or you'll slowly open my door and walk up to my bed and that I'll hear your sweet voice saying, 'Mama?' The pain of losing a child is "indescribable," Maggie added. "And yet, you have shown us in multiple ways that you are with us," she continued. "It's not the same joy as holding your hand or hearing your voice, but there is an unexplainable joy that only comes with knowing you are with Jesus. That you are in our true home. And that you are very, very happy." Influencer Paul Kim's Family Guide: Meet His Wife Maggie and Their 6 Kids Maggie's husband grabbed the attention of his followers on December 21 when he revealed Micah was in a hospital and on life support following a "medical emergency." Doctors gradually reduced life support, with Micah's lungs showing slow improvement on a ventilator. A subsequent MRI, however, revealed severe brain damage.

A GoFundMe campaign was also launched to support the family amid mounting medical costs. On Thursday, January 1, Paul confirmed his son had died on New Year's Eve after contracting a severe case of the flu. "Thank you for all the love, prayers and compassion that a countless number of you have shown us," Paul shared via Instagram on Thursday. "May God truly bless you. Your prayers for Micah were answered, but in a different way than what we had all hoped for. God healed and welcomed him into eternal life. He is where we all want to be."

"I know you are running into the arms of every Saint you meet with that big grin and saying, 'Hi, I'm Micah.' It's easy to picture these things because this is what you did when you were alive on earth," she wrote via Instagram. "Please continue to visit me and help mama keep going. You were always such a good helper and eager to make me smile. And I will keep asking for your help. My boy. I am so proud of you." Maggie continued, "Yesterday was the Solemnity of Mary, Mother of God. I was reminded of how much you loved singing the Ave Maria after our prayers and how you said 'Mama Mary is the goodest girl in the whole entire world.' Well, now you're in Heaven with her. And I'll be there soon. Hold her hand until I get there."
