Who Are We?

Let's start with who we are not. For all who believe in Jesus, the old, sinful self is dead and we are no longer slaves of sin (Romans 6:3-7).
Now for who we are. We are born again, born of God's Spirit (John 3:3-8). We are the holy temple of God's Spirit. Jesus and His Father have made their home in our hearts, and they're not moving out (John 14:23, Hosea 2:19). God has given us spiritual life in Jesus (1 John 5:11). Jesus described this life as rivers of living water flowing out of our hearts (John 7:38). Sign me up! Oh yeah, I'm already signed up.
The Christian life is about living according to who God has made us to be. Ephesians 4:22-24 says to "put off....the old man"--the old lifestyle and thought patterns of that sinful dude who died--"be renewed in the spirit of your mind"--line up our thinking with God's truth--"put on the new man which was created according to God, in true righteousness and holiness." I think this means that, in total dependence on God, we live as the righteous, holy people that we are in Christ.
A personal example: My old, sinful self had a habit of withdrawing from friendships if things started to get rocky. As soon as fear of rejection set in, I'd be looking for a place to hide. Or a safe distance from which I could examine the other person's faults and deem them unworthy of my company. Mind renewal: There are no loser Christians. In Christ I am amazing; and I am able to see His love and wholeheartedly share it with others. My brothers and sisters in Christ are amazing, and able to receive His love and share it with me, wholeheartedly. In the unlikely event of rejection, Jesus will be there for me (John 9:35-37), and He understands rejection (way too well, see Isaiah 53:3). Hey, this train of thought could lead to joy!
