An age-old question for people is, "What does God want from me?" People have offered sacrifices and kept various rituals throughout human history in attempts to please God, or various gods. Some of these efforts are extreme and others are more philosophical in nature.
Religion—including Christianity—is mostly comprised of efforts to please God or lead a life that pleases God. This might range from trying to appease God's wrath to seeing God as a benign and distant ruler of heaven.
Jesus answered this question once and for all, yet many of us misunderstand it. Christian believers who are well-versed in what the Bible says, understand that Jesus died to abolish the power and penalty of sin once for all.
But many Christians continue to try and live in some form of obedience to God through prescribed efforts at goodness. The obedience God is looking for isn't accomplished through external acts of goodness, it goes deeper than that.
For this reason, when Christ came into the world, he said, “‘You did not want sacrifices and offerings, but you prepared a body for me. You did not approve of burnt offerings and sacrifices for sin.’
Then I said, ‘I have come! (It is written about me in the scroll of the book.) I have come to do what you want, my God.’ ” [vss 5-7]
In this passage Christ first said, “You did not want sacrifices, offerings, burnt offerings, and sacrifices for sin. You did not approve of them.” (These are the sacrifices that Moses’ Teachings require people to offer.)
Then Christ says, “I have come to do what you want.” He did away with sacrifices in order to establish the obedience that God wants. [vss 8-9]
(Hebrews 10:5-9 GW) [Context– Hebrews 10]
I have come to do what you want, my God
Review the Scriptures above as you answer the following questions
Why do you think we're told what is said in the Psalms [Ps 40:6-8] was from Christ?
What are we told in this text is the purpose for Christ's coming?
Where is this illustrated by Jesus in the gospels? [hint– look towards the end]
Why did the sacrifices need to be set aside to "establish... obedience..." that God wants?
What type of obedience is God looking for? The answer is shown by His Son Jesus, the Messiah (Christ), the savior of the world. Jesus came to do the Father's will not His own. As it says, "I have come to do what you want, my God."
This is made clear by the Lord's struggle in prayer in the garden of Gethsemane (Matt 26:36-46), where Jesus asks three times if "this cup" of suffering could be set aside. Each time, Jesus submitted His will to the Father.
This is our illustration, our example for the obedience God wants. Not external acts of goodness but the surrender of our lives to Him.
Jesus' once-and-for-all sacrifice on the cross brings a freedom from the impossible burden of perfect obedience required under the Law. God is not requiring acts of obedience we can do for Him but calling us into a relationship of trust (faith).
This relationship of trust is an ongoing internal and spiritual work enabled by God's Spirit dwelling in us as believers. This is what Jesus meant about denying yourself and taking up your cross in order to follow Him (Matt 16:24).
