Breathe and Worship to This

I'm satisfied by Your love so completely.
How can I thirst for the praises of men?
There's nothing I need that You haven't provided,
and no one can offer me peace like You can.

Jesus, You're more than enough,
sufficient for me:
all I have needed You've given for free.
Your love is enough,
don't need man's applause,
I know what I'm worth: I remember the cross.

I'm sustained, O Lord:
when Your Light surrounds me the world fades away.
I'm sustained, O Lord:
my heart knows Your love like it flows through my veins.
Such peace and contentment I've found in Your grace:
I can't think why I ever complained.
You love me: what more could I want?
I am sustained.

My husband was playing this song tonight,
and as it always does, it soothed my soul.
