Paul says in 1 Corinthians 5:11-13 that biblical Christians are not to associate with anyone who claims to be a Christian but lives a very immoral lifestyle. He gives examples such as sexual immorality, greed, idolatry, slander, drunkenness, and swindlers. He is referring to people who, at one point, lived a biblically Christian lifestyle, but have since "fallen off the wagon," so to speak. His purpose in telling the church at Corinth not to associate with these people was to show them how far they had strayed and, ultimately, to bring them back to a godly lifestyle. It sounds harsh when you read it, but Paul was also always the first to welcome back a wayward brother.
The point of all this is as follows: my prayer for myself is that I would never take my faith for granted. I never want to be the kind of Christian who uses my faith as nothing more than a label. I want more than that. I want biblical Christianity. The kind of faith in Christ that gives me the courage an boldness to be unashamed. The kind of faith that prevents me from ever claiming there is any god or power or entity other than the One True God. The kind of faith that I could die for; because I know, beyond a shadow of a doubt, that Christ is the only way to God. The kind of faith that I'm not afraid to proclaim from the rooftops because I want everyone to experience Christ and how fulfilling a relationship with him can be.
That's the Christianity I want. That's the level of faith I pray for myself every single day. I want to be unashamed and unapologetic of my faith. I want Christ to be my whole life, the basis of who I am. I don't want someone to look at me and question the genuineness of my faith. I want them to look at me and know where I stand.
