During His preaching ministry, Jesus described the nature of God. But before doing so, did He have to lay a foundation and convince people that God exists? Or had oral tradition and the Old Testament already convinced most people that God exists?
Reason I ask:
- Christians typically credit Saint Thomas Aquinas' 'Quinque viae' as the best arguments for the existence of God.
- But I assume that most of Jesus' contemporary followers must have already believed in "a god", because if they didn't then Jesus would have needed to spend a good deal of His effort persuading the masses that "a god" (that is any god) exists, as opposed to "the God" that He existed as in the Holy Trinity.
