Analysis of Heart of God

O great heart of God,
Once vague and lost to me,
Why do I throb with your throb to-night,
In this land, eternity?

O little heart of God,
Sweet intruding stranger,
You are laughing in my human breast,
A Christ-child in a manger.

Heart, dear heart of God,
Beside you now I kneel,
Strong heart of faith. O heart not mine,
Where God has set His seal.

Wild thundering heart of God
Out of my doubt I come,
And my foolish feet with prophets' feet,
March with the prophets' drum.
