Any death is hard. Any tragedy is hard. This one especially tugs at all of your emotions and compassion. I have always been a fan of Steven Curtis Chapman's music, especially when I was a little younger. One of my favorite songs of his is A Miracle of Mercy.
Their family is really hurting right now with the tragic death of one of their adopted daughters. (I don't mean tragic like tragic as if it caught God by surprise (it didn't), but how we feel about it on this side of heaven. Tragic. Hard.) I do pray that the Scripture-informed songs on this very topic bring comfort to their hearts. Lyric like Grieve with hope or Only God is God.
These sobering reminders are wake-up calls that life is short... so fleeting.
Pray for them and fix your eyes even more firmly upon Christ, your hope and strong comfort in the storms of this life. One day, all the tears of God's children will be wiped away.
Pray for the big brother.
