Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 2 Corinthians 5:17
When we become in Christ, we are Born-again. Inside we have become new. Unfortunately, our circumstances and our thinking doesn’t magically line up with that decision. It takes work to get our thinking in line with God’s. When we believe right, we will think right. And believing right will change our cirumstances.
