Romans 12:1-2 NIV
1 Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. 2 Do not conform 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.
Introduction
God does not desire us to present a dead animal sacrifice, but desires for us to be a living sacrifice. What does it meant to be a living sacrifice? It means to daily lay aside our own desires and follow after Him. It means to live by the power of the Holy Spirit in order for the fruit of the Spirit to manifest in our lives. This is our “spiritual act of worship” unto the Lord: we live by the Spirit by renewing our minds in God’s Truth.
Let us consider these verses from Scripture as we examine what it means to renew our mind. Most individuals operate out of the belief that when something (activating event) happens, they are to simply respond (reaction). Hence, the equation of A=C. For many people, this activating event will elicit a natural reaction.

Activating Event (A) | Possible Reactions (C) |
Someone steps/stands on your foot while waiting at the bus stop. |

The Power of the Enemy is in the Lie
As Christians, we know that there is only one belief system that is Truth and all other belief systems are lies. If Satan can convince us to believe lies about ourselves, lies about others and lies about God, we will be under his control, even while he is bound. This is why it is crucial for us to renew our minds.

- 1 Peter 5:8 NIV
How Do We Renew Our Minds?
First, we must realize that there are many lies we believe on a regular basis. These lies inadvertently and sometimes maliciously come from culture, friends, family, and even the church. God wants us to expose these lies and transform our minds with His Truth.
There Are Two Types of Lies
- Conscious Lies. These lies are easily detected. Maybe before you knew Christ, you used to berate and cuss out others to bring them down. Or perhaps you used to steal. This behavior existed because of your belief system. Clearly, since they were sinful acts, these behaviors originated from lies in your belief system. Therefore, as a follower of Christ, you now must realize that these behaviors must cease because God commands not to conform to the world’s mold but to His. These “conscious” lies are dealt with based on the Christian’s desire to come broken before God and repent of their sin.
- Subconscious Lies. These lies are not as easy to detect. They can be subtler and usually result from patterns of thinking. These lies can be ingrained in you and eventually become part of your personality.
Turning Lies into Spiritual Truth
After we recognize the lies in our belief system, we must choose to believe the Truth! The only way for someone to stop believing lies and begin to believe truth is not through positive thinking. We cannot believe the Truth unless we know the Truth.
The Truth is Found in God’s Word
We must begin by asking what God’s word says about a particular situation. For example, if we are believing lies about ourselves in regards to issues of self-worth and self-image, we can turn to Genesis 1:27 NIV, Psalm 139:13-14 NIV, Isaiah 43:4-5 NIV, and Romans 8:37-59 NIV to understand that our worth is a result of who we are in Christ.
Conclusion
We must remember that all behavior we exhibit is a function of what we believe at that moment. If we are believing a lie, then our behavior or reactions to circumstances in our lives will reflect this lie. By understanding the command to replace the lies in our belief system with spiritual truth, we are on the road to recovery and healthy living in Christ. We will begin to see victory in our walks with God once we begin to break free from these lies.
