I am not a Bible scholar so I won’t do a deep dive into a passage here (I teach Bible study classes at my church where I attempt that). I would tell you that if you want to see what a Grown Up Christian looks like, then your best to look to the Sermon on the Mount (Matthew 5-7), John 15, and Colossians 3.
The verses that speak to me the most about maturity are the ones that pinpoint the dying of the old self and the putting on of the new self. Galatians 2:20 starts off, “I am crucified with Christ and I no longer live…”Matthew 16:25 talks about gaining life by losing it for Christ’s sake. Ephesians 4:22-24 says to “put on the new self, created to be like God in true righteousness and holiness.”
In these verses, there is no question what your life is supposed to look like. There is no temptation to just sprinkle a little moralism, some self help mantra, and some vague religiosity over your life. The call is severe and drastic and the end result is noticeable, powerful, and profound.
Your commitment to Christ means your commitment to a radical change in your life. The old self is slowly being put to death and the new self is being grown, fed, and watered through Christ’s work in you and your training in spiritual growth and maturity.
This is no mere add on to your life. No “nice thing” to do. This is your life now if you have Christ.
What are you doing with your new life?
