The answer to this question could change your life.
Both within and outside the Church, there is a confusion: What does it mean to be a Christian? Many non-Christians are turned away from the Church because of what they think it means to be or not be Christian. Many self-proclaimed "Christians" are using the label incorrectly, gleaning a false sense of security from it and wielding it in a manner that damages anyone within arm's length.
My Observations
I observe that regarding Christianity, there are basically six kinds of people, relative to Christianity, though sometimes these categories overlap a little. These terms are my own, used in an effort to clarify the positions:
Anti-Christians are those who have a correct or incorrect view of Christianity and who are hostile toward those who bear the label. There are most often non-Christians, but some so-called Christians become so cynical about the Church that they might fall into this extreme category.
Non-Christians may or may not be hostile to Christianity, and they may or may not have a correct understanding of Christianity. Some have consciously chosen not to follow the lifestyle of a Christian; others have not yet understood what it means to be a Christian.
Traditional "Christians" are those who were born into the Church or Christian culture, using the label as a part of their identity, but without bearing the fruit a Christian's life bears. Usually their religion could be described as "lifeless," or sometimes "legalistic." These are often found in Orthodox, Catholic, or more conservative Protestant denominations, though they can be a part of any fellowship group.
Apparent "Christians" are those who are easily mistaken as Christians, due to their zeal and fervor. Some of them demonstrate very spiritual behavior, including prayer and emotional worship; others boast long lists of good-deeds and generous sacrifices done in the name of Jesus. Thus, they appear to be bearing the fruit of a Christian life, but they lack the relationship with Jesus and will not be able to sustain such a lifestyle from their own strength for very long. Mistaken Christians might also fall into this category.
Mistaken "Christians" are those who call themselves Christian, but who have exchanged the truth of the Gospel for a lie. These could include Mormons (Church of Latter Day Saints), Jehovah's Witnesses, Christian Scientists, Unitarian Universalists, and many others. On the surface, they often seem to share the same core beliefs with Christians, but in each case there is a fundamental truth that has been changed or discarded. Many of them are trapped in this false belief and have no understanding of the Truth they are missing.
True Christians are those whose lives clearly reflect the death and life of Christ Jesus. Their lives are not from their own strength (for their lives were crucified with Christ when He died to defeat sin and death out of His love for us), but through faith they have surrendered to the life of Jesus, of His Holy Spirit, living through them. This surrender causes a noticeable life-change, which could be called "repentance." They allow the Spirit to live freely in them, to the glory of the Father. They are in a real, personal relationship of love with Jesus, who drives away the fears they once had.
What is a Christian?
According to the Bible, what does it mean to be a Christian? We will see that the definition is inextricably wrapped up in the Person and Life of Christ Jesus, as well as in the idea of the Trinity.
Chapter 11 of the Book of Acts, verse 26, records that the disciples were first called "Christians" at Antioch. Study of this passage shows that these were a group of new believers of primarily non-Jewish background who studied and gathered together for a year. Because of their new lifestyle, they were called "Christians" or "little Christs," based on the observation that they lived like Christ Jesus, or that they imitated the life of Jesus.
The Book of Galatians is appropriately the next place to turn, for Paul is chastising the Galatian Christians for losing sight of the original Gospel, (literally "Good News"); thus, the entire book is a discussion of the true Gospel. Verse 20 of Chapter 2 spells it out using Paul, himself as the example: he reminds the Church that Christians have been "crucified with Christ," that it is no longer them who live, but Christ living in them. That life is described as being lived "through faith" in Jesus, who, we are reminded, lovingly gave Himself up for us, as was previously mentioned in Chapter 1, verse 4. This was according to the will of and for the glory of God the Father (verse 5). Chapter 3 continues the reasoning, explaining in verses 13 and 14 that Christ became cursed to break the curse of sin on us, and this allowed us to receive His Spirit. Chapter 4 reminds us that our holy Savior was born in human flesh in order to adopt us as children in God's family that God's Spirit might dwell in us (verses 4, 5, and 6). Such a life bears good fruit (Galatians 5:22).
Many other parts of Scripture reiterate this truth, this definition of a Christian, and of the Gospel that makes a person a Christian. See, for example (these are only a few of many):
On being a Christian: Matthew 16:24, Luke 6:40 and 14:26, John 14:10-20 and 15:12-19, James 1:17-27 and 2:17, and Revelation 2:2-5
On the Gospel: John 3:16-17, Acts 2:29-33, 38-39, Romans 1:2-6, Ephesians 1:3-14, Colossians 1:12-22, and 1 John 4:7-21.
In other words, a Christian is not someone who decides to live as a Christian. A Christian is one who decides to believe the Gospel and to surrender his (or her) life to the Lord, that Jesus might live in and through him (or her). Jesus came to reveal His Father and to glorify His Father. If Jesus is living in us, we do the same thing. Therefore, what is a Christian? A Christian:
1. Accepts and returns the love and grace of God as embodied by his (or her) personal Friend, Jesus.
2. Does not live anymore, but surrenders daily to let the Spirit of Jesus live freely in and through him (or her), to the glory of the Father.
3. Has a life that is proof of the truth of the Gospel and that bears spiritual fruit.
And what is the Gospel? The Good News (the Gospel) is that:
1. God loves us so much that He intervened when our sin separated us from Him!
2. He made a way by sending His Son Jesus to live as a perfect human who would pay the death penalty for our sins, allowing us to die to the bondage of sin.
3. The Father raised His Son and offered us new life with Him, putting His Spirit in us that we could be in eternal relationship with Him as His children, if only we will believe and surrender to His love.
So, are you a Christian?
Do you know Jesus as a Friend, or just know about Him as an idea?
Do you try hard to live as a Christian, or do you let the Spirit live in and through you?
Was there ever a noticeable change in your life (marking your total surrender), witnessed by you and by others?
Does your life reflect the unique life of Jesus, or does it look like everybody else's life?
Does your life bear fruit for the glory of God, or is religion just a rote, token part of your existence?
Are you afraid of many things, or does the love of God give you confidence and boldness?
Is this Truth the Gospel you know, or have you been following one that has been edited or simplified?
Do you think the world might look a lot different if everyone in the Church, everyone calling himself (or herself) "Christian," would surrender to a Jesus personally known and loved, letting His Spirit live freely in him (or her) to the Father's glory, bearing fruit in keeping with repentance?
