This psalm [Psalm 128], which is a blessing on the family, is also a blessing on the nation, because as the family goes so goes the nation. The blessing of a nation starts with godliness in the hearts of parents. Such parents fear God and obey his commandments. Their strength flows to the children through the contentment and peace it produces in the family.
From solid families strength flows to the nation. From solid, godly families come workers who will build up the nation, parents who will raise godly children, and children who are our hope for the future. Without such families the future is dark. From such families the nation and the church will find strength.
