Beginning in Romans chapter 1, Paul reminds you that you are to yield your full personality to Christ. And that your spiritual service is that which is pleasing to God. You're not perfect? God is rich in mercy-- He has plenty of it. This means that God's compassion will never fail you.
Jesus and God are one. Therefore, your Savior has an ultimate level of compassion. So much so that some say that compassion is Jesus' middle Name!
I appeal to you therefore, brothers and sisters, on the basis of God’s mercy, to present your bodies as a living sacrifice, holy and acceptable to God, which is your reasonable act of Worship. Do not be conformed to this age, but be transformed by the renewing of the mind, so that you may discern what is the will of God—what is good and acceptable and perfect. Romans 12:1-2
As Paul begins a new and third section of Romans, he highlights the the nitty-gritty of what we are to do as Christians. First, choose to have your personality transformed by Holy Spirit; accept the changes Spirit makes. Second, take Christ-like Love as a compass, so to speak.
A Christian does not have a lot of don't-dos because Christ's Presence is the compass which guides you in being led by Holy Spirit. This is how the removal of degrading traits, such as a gossipy tongue, can occur. Christ affirms your transformed personality. A heart-warmed soul relies on Holy Spirit. You'll be given clear warnings to avoid faith's pitfalls.
Over time your personality gains quiet joy, solid Peace, and clear Christ-like thinking.
