    I Know You Now

    by: 4him

    I looked at faith
    I almost walked away
    But I looked again
    I found the nerve to close my eyes and say the words
    To ask you in
    And I heard no heavenly choir
    No angels in whit attire
    i got no amazing super hum omnipresent pow but....
    CHORUS
    I know You now
    I know You now
    I know You're in my heart
    I know You now
    Beyond the shadow of a doubt
    I know You now
    I look at peace, that once was out of reach
    And now it's here
    i read Your word that some believe is so absurd
    But I hold dear, yea
    'Cause You loved me with your dying breath
    You saved me when You conquered death
