The Gospel vs. Religion (by Tim Keller)

The gospel is "I am accepted through Christ, therefore I obey" while every other religion operates on the principle of "I obey, therefore I am accepted." Martin Luther's fundamental insight was that this latter principle, the principle of 'religion' is the deep default mode of the human heart. The heart continues to work in that way even after conversion to Christ. Though we recognize and embrace the principle of the gospel, our hearts will always be trying to return to the mode of self-salvation, which leads to spiritual deadness, pride and strife and ministry ineffectiveness.

For example, ministers derive more of their joy and a sense of personal significance from the success of their ministries than from the fact they are loved by God in Christ. Why? Their hearts are still operating on the principle--"if I do and accomplish all these things--then I will be accepted." (cf. Harold Abrahams in Chariots of Fire- "I have 10 seconds to justify my existence.") In other words, on one level, we believe the gospel but on another level we don't believe.

So why do we over-work in ministry and burn out? Yes, we are not practicing the Sabbath principle, but the deeper cause is unbelief in the gospel! Why are we so devastated by criticism? The person whose self-worth is mainly in his or her ministry performance will be devastated by criticism of the ministry record because that record is our very self and identity. The fundamental problem is unbelief in the gospel.

At the root, then, of all Christian failures to live right--i.e. not give their money generously, not tell the truth, not care for the poor, not handle worry and anxiety--is the sin under all sins, the sin of unbelief, of not rejoicing deeply in God's grace in Christ, not living out of our new identity in Christ.
