According to J. Vernon McGee, this psalm has been used on several important occasions. It was used at the inauguration of President Eisenhower. Two Bibles were used. One of them was George Washington’s Bible, and it was opened at Psalm 127.
This wisdom psalm explores our need for the Lord. The things we build in this life and spend our time on mean nothing if God isn’t in it. More specifically, the act of getting up early in the morning and feeding ourselves should give us fuel to serve the Lord. If we aren’t living this life for Him, that energy only sustains us in a miserable state. It’s all in vain.
Like children bring contentment (verse 3), a life dedicated to the Lord brings satisfaction. This is the reason why God gives us sleep and provides us with material resources (verse 2). We are to take all of those blessings and pour them out to be used for His Kingdom. This is what it means to practically live out “presenting your bodies as a living sacrifice.”
As Nancy deClaissé-Walford writes, the “children” from verses 3 and 4 could refer to an expression of God’s love birthed in our souls.
“But the term “children” includes far more than our biological offspring. The fruit of our womb may be a project to end hunger in our community, the hope and encouragement we give to the seniors who wait anxiously every week for our visits, the changed lives of teens who come to our church on Friday evenings instead of cruising with their friends. These children, these “building projects,” are the sources of our contentedness in life, the purpose for which God gives us sleep.”
