The issue of 'Trust'

Easy to say,
Easy to do for a child below 18 months.
...but not for grown-ups.

The older I am the harder to trust...
Despite of all the miracles, greatness, awesomeness shown to me...
I just forgot...
just like that...
Forgot that God IS God.

No wonder Jesus said the one who can enter the Kingdom of God are those who has the heart of a child.

If I can't trust what my eyes can see, how can I trust what my eyes can't see?
