17 Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!
From DSC:
Being transformed in our thinking is one of the LORD’s key goals for us and one of the areas where He is active in our lives. (Also see Romans 12:2.) Our thinking impacts many things, including our behaviors, attitudes, and perspectives.
But my reflection here is especially meant for new believers in Christ. This process of transformation takes time. Don’t expect immediate changes in some areas of your life. After you received Christ into your heart, you may doubt that anything has changed. But you will begin to see the world, God, and others differently over time. (Reading scripture regularly helps this process along.)
