Being willing to let the Lord change us is an important part of our growth. In Romans 12:1-2, God tells us three things on how we can partner with Him for internal and external change. 1) Present your life, your work and your ministry to Him, 2) Don’t follow the pattern of the world, as you might miss out on the radical changes He wants for you and 3) Renew your mind. This can be done by staying in the Scriptures and praying.
Romans 12:1-2 (KJV) And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will of God.
