What level of faith do we need?

I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there' and it will move. Nothing will be impossible for you."Matthew 17:20

I'm of the opinion that it is not GREAT faith that moves mountains - at least not OUR great faith...Rather, God's great faith.

I was thinking this morning that when it comes to faith, my role is to simply believe that God can do something, and then watch Him do it. My faith is in what God can do and it doesn't matter how much I can't do. (OK, a bunch of analyticals just blew a gasket on that one.) What I mean is, if my level of faith is based on what I know is possible for God, then all I have to do is believe He can and will do it and He will act according to what His will is. I don't always know His plan, but I do know this:

“ For My thoughts are not your thoughts,
Nor are your ways My ways,” says the LORD.
“ For as the heavens are higher than the earth,
So are My ways higher than your ways,
And My thoughts than your thoughts.
“ For as the rain comes down, and the snow from heaven,
And do not return there,
But water the earth,
And make it bring forth and bud,
That it may give seed to the sower
And bread to the eater"
Isaiah 55:8-10

My fears, uncertainties, and insecurities, although real emotions, are second to the truth. God has my best in mind.
