My heart is ready, O God

My heart is ready, O God; my heart is ready.
    I will sing, I will sing your praise.
Awake, my soul; awake, O lyre and harp.
    I will awake the dawn.

Give us help amid our difficulties,
    for human aid is vain.
With God, we shall do bravely,
    and he will trample down our foes.

Psalm 108.2-3, 13-14
