I've always understood it to basically mean the Father choosing to give us peace, joy, clarity, direction, health, etc. through people, things, words, thoughts, feelings, or any other way He chooses.
really, as I think about it, I think anything He gives to us is a blessing.
because He gives good gifts...
and sometimes even our storms get us exactly where He wants us.
and His ways are perfect.
so in short...
bless= give something to; or give of yourself to
What do you think?
