Romans 12:1-2

Therefore, brothers and sisters, in view of the mercies of God, I urge you to present your bodies as a living sacrifice, holy and pleasing to God; this is your true worship. Do not be conformed to this age, but be transformed by the renewing of your mind, so that you may discern what is the good, pleasing, and perfect will of God.

Galatians 5:22-25

But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. The law is not against such things. Now those who belong to Christ Jesus have crucified the flesh with its passions and desires. If we live by the Spirit, let us also keep in step with the Spirit.

Proverbs 4:23-24

Guard your heart above all else, for it is the source of life. Don’t let your mouth speak dishonestly, and don’t let your lips talk deviously.
