What does the Bible say about being a living sacrifice unto the Lord?

Sacrifice is defined by Nelson's Bible Dictionary as "The ritual through which the Hebrew people offered the blood or the flesh of an animal to God as a 'substitute payment' for their sin." Then what is a living sacrifice? How are we to offer our lives as a sacrifice to God?

The following verses describe what the Bible says about being a living sacrifice unto the Lord:

Romans 12:1-2 says, "Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God - this is your spiritual act of worship. Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is - his good, pleasing and perfect will."
1 Peter 2:1-5 reads: "Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation, now that you have tasted that the Lord is good. As you come to him, the living Stone - rejected by men but chosen by God and precious to him - you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ."
Ephesians 5:1-2 says, "Be imitators of God, therefore, as dearly loved children and live a life of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God."
2 Corinthians 4:6-12 reads: "For God, who said, 'Let light shine out of darkness,' made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ. But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us. We are hard pressed on every side, but not crushed; perplexed, but not in despair; persecuted, but not abandoned; struck down, but not destroyed. We always carry around in our body the death of Jesus, so that the life of Jesus may also be revealed in our body. For we who are alive are always being given over to death for Jesus' sake, so that his life may be revealed in our mortal body. So then, death is at work in us, but life is at work in you."
Hebrews 13:15-16 says, "Through Jesus, therefore, let us continually offer to God a sacrifice of praise - the fruit of lips that confess his name. And do not forget to do good and to share with others, for with such sacrifices God is pleased."
Psalm 51:17 declares: "The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise."
