Reflecting on today's Solemnity, I kept returning to one thought~that Mary's Assumption into Heaven is a promise of what awaits us. I don't mean necessarily in the way she "died", but that she resides now in heaven body and soul, as does her Son. While there are many souls in heaven, there are only two who are there body and soul, and those are Jesus and Mary.
I like to think and reflect on this sometimes. God loved humanity so much that he took on a human body through that of another human body, thereby sanctifying humanity. God loves humanity so much that He has promised to return our bodies to us, glorified, at the end of time.
The Assumption of Mary is a beautiful reminder of what God has in store for those who love Him.
