In the readings for the 16th Sunday in Ordinary Time, God constantly inundates mankind with His goodness and repeatedly intervenes in mankind's sinful behavior to give one more opportunity to choose His way rather than the way of sin.
In the first reading, Jeremiah expresses God's warning that people who have led God's flock astray will be punished. However, God will gather the scattered. The Exile in Babylon was punishment, but God will bring them all back because He wants to develop a people who will receive and live His word.
