For the prophet Jeremiah, the people of Israel were formed by the Lord. He believed that God intended to reveal himself in a collective manner, where the primary relationship would be between the Lord and his favored people. With the entry of Jesus into history, all of that changed.
This word came to Jeremiah from the LORD:
Rise up, be off to the potter’s house;
there I will give you my message.
I went down to the potter’s house and there he was,
working at the wheel.
Whenever the object of clay which he was making
turned out badly in his hand,
he tried again,
making of the clay another object of whatever sort he pleased.
Then the word of the LORD came to me:
Can I not do to you, house of Israel,
as this potter has done? says the LORD.
Indeed, like clay in the hand of the potter,
so are you in my hand, house of Israel.
Jesus gave his life so that we, individually, could be saved. But there is a collective aspect of our walk with him. It is his Church, given to the disciples by Jesus to protect us from falling into error. It also provides us with a community of believers to strengthen one another.
Jesus is the potter and we are the clay. If we open our hearts to him, he will shape us in his own image.
