"But Mary treasured all these things, pondering them in her heart." - Luke 2:19
Mary had numerous miraculous experiences and it was extremely hard for her to explain them or convince anyone.
When we encounter heavenly experiences, we are in similar situation - it's quite hard to explain it to anyone. Even if we do, hardly anyone would believe us. As a result, we will end up treasuring those wonderful experience(s) in our hearts like Mary did.
Have faith like Mary did and believe.
