I embraced a lot of bad doctrine during those years, and yet I knew deep down that much of the theology didn't really square with Scripture. I just didn't know Scripture well enough to argue against Charismatic doctrine. But I did know that I had no claim to heaven apart from the shed blood of Jesus Christ.
Trusting in Christ rather than self-effort marks a true Christian. Although we must pay attention to other points of doctrine (particularly the sufficiency of Scripture), the basic Gospel must underscore everything else. The true Christian knows his depravity, and therefore has no option other than to rely exclusively on Jesus to atone for his sin.
In contrast, many false converts have great difficulty understanding the severity of their sin. Oh, they may give lip-service to the concept, but they secretly believe that they either took part in becoming Christians or have some responsibilities in maintaining their salvation. They sing about God's grace, but they can't really believe that He has done all the work. They feel driven to contribute something.
The apostle Paul addressed this prideful attitude in the letter to the Galatians. Of course I can't copy the entire epistle here, but consider this passage as an example:
O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified. 2 Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? 3 Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? ~~Galatians 3:1-3 (ESV)Charismatics, Catholics, proponents of contemplative prayer and adherents of psychology all can fall into this category of false converts. All these groups (and probably others) subtly add human effort either to salvation itself or to sanctification while minimizing the doctrine of depravity. In fact, some of them actively seek to bolster self-esteem, teaching that Jesus died for us because of our worth. The focus, in one way or another, reverts to man's ability to earn God's favor--directly contradicting the message of the Gospel.
Other false converts minimize the doctrine of sin, either by claiming that they're free to sin because of Christ's death on the cross (which paid for their sin) or by manipulating Scripture to excuse their particular sin. They violate the Gospel by refusing to let it conform them to His Holiness. They expect God to make them feel good, but reject any thought of surrendering their lives to Him.
The following passage from 2 Peter describes the attitude of false teachers, but I believe it also applies to others who use a faulty understanding of grace to justify sinful behavior.
19 They promise them freedom, but they themselves are slaves of corruption. For whatever overcomes a person, to that he is enslaved. 20 For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. 21 For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. 22 What the true proverb says has happened to them: “The dog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.” ~~2 Peter 2:19-22 (ESV)Gay Christians (particularly those who once served as leaders in the ex-gay arena before going back to homosexuality), female pastors and elders and emergent church types provide the most prominent examples of those who minimize the gravity of sin. But by trivializing sin, they also trivialize the precious blood of Christ. Additionally, they pull the emphasis away from the Lord's glory and on to how He can satisfy them.
I've merely given an overview of false conversion today, but I expect to explore the topic more in the future. As we all examine ourselves to make sure He has genuinely saved us, may we keep our gaze on Christ, giving Him all the glory and adoring Him for saving wretches like us. May we adorn His Gospel.
