As I was reading Psalm 119, I became fascinated by verse 164, which says "Seven times a day do I praise thee because of thy righteous judgments."
Recall that this is the longest chapter in the Bible with 176 verses, where practically every verse highlights the attributes of God's Word, all from the very personal perspective of its author.
The Word of God can literally save a life: George Wishart was the Bishop of Edinburgh in the 17th century. Wishart was condemned to death and would have been executed. But when he was on the scaffold, he made use of a custom that allowed the condemned person to choose one psalm to be sung, and he chose Psalm 119. Before two-thirds of the psalm was sung, his pardon arrived, and his life was spared. [Source: blueletterbible.org]
Back to verse 164 - what makes a person so emphatic in their declaration of praise? Well, one quick answer is already noted in the verse - it's because of God's righteous judgments. He has seen that God has always done right by Him; He has never left or abandon him.
