Ephesians 4:23-24 and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.
When you surrendered your life to Jesus Christ, you became a new creation (2 Corinthians 5:17). A major transformation occurs when someone takes this step. Along with that transformation comes a new heart. With a new heart comes new desires. With new desires comes renewed thinking.
The thing about obedience to God is that it all begins with right thinking. If we have any hope of following Christ we can’t do it on our own. We need His help to obey and we can only know what it is He wants us to do if we have been transformed by the renewal of our minds (Romans 12:2). We have to seek after the truth that’s only found in Him.
At some point in time the truth of God’s Word really penetrates your soul and you just know the truth for what it is. It becomes so clear that you can’t believe that you never embraced this truth before. This truth sets you free! (John 8:32) With a new heart and a new mind there’s a new life, one free from the burdens of this world and from the taskmasters of fear and shame.
A new mind is a clean slate to start over with. Instead of allowing your mind to be consumed by the things of this world, you have the opportunity to allow the Holy Spirit to fill it with what is right and good and pure.
