Trust in him at all times; ye people, pour out your heart before him: God is a refuge for us. Selah.  Psalms 62:8

The word  “pour” plainly signifies that the heart is full of grief, and almost afraid to empty itself before the Lord.  What does he say to you?  “Come and pour out all your trouble before me.”  He is never weary with hearing the complaints of his people; therefore you should go and keep nothing back; tell him everything that hurts you, and pour “all your complaints into his merciful bosom.”  That is a precious word:  “Pour out your heart before him.”  Make him your counsellor and friend; you cannot please him better than when your hearts rely wholly upon him.  You may tell him, if you please, you have been so foolish as to look to this friend and the other for relief, and found none; and you now come to him, who commands you, to “pour out your heart before him.”
