My husband thinks he knows me so well. "I know you like a book!" Isn't it... "I read you like a book?" Yes, he thinks he "knows" me better than I know myself. But, really when I sit down to think about myself as to what makes me tick...God is the only One who knows me better than my husband knows me or even than I know myself.
I remember an event quite some years ago, I asked a friend if she'd be interested in attending to see and hear this famous movie star, now a Christian. She said, "I'm not going to pay money to listen to someone tell me how to live my life that's been married 8 times!" Wow! That set me back a bit. I wasn't ready for a response like that. Of course, I should have said and couldn't think fast enough, "She's not the same person she was...she's a new creation in Christ Jesus, just like anyone who puts their trust in the Lord."
Same with my life. I think people tend to look at me the same way before I became a believer. I'm not that person anymore. As of May 30, 1995, Carolyn became new, the old things of Carolyn are gone.
"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 NKJV)
