Charles H. Spurgeon on Psalms 119:10

With my whole heart have I sought thee. Sincerity is in every expression; the heart is open before God. The young man can so speak to the Searcher of hearts... Let us consider the directness of this kind of converse with God. We use round about expressions in drawing nigh to God. We say, With my whole heart would I seek thee. We are afraid to be direct... See how decided in his conscious acting is the young man before you, how open and confiding he is, and such you will find to be the characteristic of his pious mind throughout the varied expressions unfolded in this Psalm. Here he declares to the Omniscient One that he had sought him with all his heart. He desired to realize God in everything. John Stephen.

Ver. 10 (first clause). God alone sees the heart; the heart alone sees God. John Donne, 1573-1631.
