The scriptures read are Jeremiah 1-3, Psalm 47 and Hebrews 3.
Jeremiah 1. Jeremiah was a good man living at a bad time: the twilight of Judah just prior to and during the Babylonian defeat and destruction of Jerusalem and the subsequent exile of its people. Jeremiah's name could mean, "The Lord exalts" or it could mean "The Lord throws" because the prophet is thrown into the deep end of events. He is not always popular with the kings he served under and spent a lot of time in prison. Jeremiah is frank about his feelings, making him one of the most personally revealing of the prophets.
God commissions Jeremiah to be his prophet before he even drew a breath. God can use a mere boy to spread his message and he will protect him from harm. Good thing, too, because Jeremiah is going to make enemies in high places.
Jeremiah 2. God's people did stick with him through the early years but lately they've been trashing the land. They have gone after other gods, gods of the fertility and human sacrifice kind. They don't see their idolatry as adultery. So here comes judgment. God's people only turn to him when things get bad.
Jeremiah 3. God sees both the northern kingdom of Israel and the southern kingdom of Judah as promiscuous sisters. Nevertheless, God in love pleads with Israel to repent, to turn her life around. We get quite a heartfelt scene of the prodigal nation returning to God.
Psalm 47. A very joyful gospel version of a very joyful psalm!
Hebrews 3. The writer is comparing Christ with Moses. Moses was a good servant but Christ built the house, which is all believers. He urges the listeners not to be spiritually deaf like the Israelites coming out of Egypt.
