What did the Trinity agree to put in the universe?
The three persons of the Trinity agreed to create the universe and to put one small planet within it, described as a speck in the midst of the universe. This counsel occurred in eternity past before anything was called into being, and their agreement set everything in motion according to the determinate counsel and foreknowledge of God.
Les explains that Acts 2:23 records Peter preaching on the day of Pentecost, saying Christ was delivered by the determinate counsel and foreknowledge of God. That verse indicates that sometime way back in eternity past, before anything was ever called into being, the triune God had a counsel. They counseled with one another. Since they were all members of the Godhead, they did not have to deliberate for a half an hour. Nevertheless, the Trinity came together and in a counseled agreement set everything in motion. The three persons of the Trinity agreed that they would create the universe and that they would put one little planet down there, just like a speck in the midst of it.
