Psalms 127 and 128 beautifully describe God’s perspective on children, which we need to recover, not only for our own happiness but also for the well-being of the world.
In the New Testament, as in the Old, the people of God were led by elders who were selected from among the people.
God has always been with his people, in various ways and temporarily in Old Testament times and later and permanently in human flesh.
When we hear the gospel and believe it, Christians are sealed with the Holy Spirit.
