Offerings in Righteousness That God Accepts
This passage deals with an age when corrupt priests despised God by offering unclean sacrifices, and with the event of God himself coming into the world to become the eternal High Priest. Through the account of Abram giving a tithe of the spoils to Melchizedek, the king of righteousness, after winning a battle, it sheds light on the true office of priest that existed even before the Law, and on its meaning.
The sermon stresses that no act or devotion that human beings offer is accepted by God without the blood of Christ. Believers do not offer animals as sacrifices; they become people who offer God offerings in righteousness through faith in Jesus' cross and resurrection. It also points out that, remembering that God does not change, we must live lives that truly fear God, not a faith of pretence.
It asks what believers should hold on to as they live, and how they should trust God's unchanging promises.
