You already have had two days when you read just one chapter and that was because those chapters were rather lengthy. Well, today you're to read just one chapter, all three verses of it! And, "No," it's not a mistake. I've checked out several chronological reading plans and all of them have just this one chapter for today. So, take time, and read and listen to God.
Psalm 133 - Unity of believers; family support and encouragement; tackling the job with everyone helping... All of these thoughts are ways to consider the message of this Psalm. It's a joy to have fellowship together, especially when your "togetherness" surrounds the Lord! God is pleased when His family love each other and work together.
Okay, so you've read this one chapter. I hope God spoke to your heart. Have you considered memorizing it? Might not be a bad idea. And, one more thing: put this Psalm to practice.
