Gospel-Driven Sanctification

As I see it, the Christian community is largely a performance-based culture today. And the more deeply committed we are to following Jesus, the more deeply ingrained the performance mindset is. We think we earn God's blessing or forfeit it by how well we live the Christian life.
Most Christians have a baseline of acceptable performance by which they gauge their acceptance by God. For many, this baseline is no more than regular church attendance and the avoidance of major sins. Such Christians are often characterized by some degree of self-righteousness. After all, they don't indulge in the major sins we see happening around us. Such Christians would not think they need the gospel anymore. They would say the gospel is only for sinners.
For committed Christians, the baseline is much higher. It includes regular practice of spiritual disciplines, obedience to God's Word, and involvement in some form of ministry. Here again, if we focus on outward behavior, many score fairly well. But these Christians are even more vulnerable to self-righteousness, for they can look down their spiritual noses not only at the sinful society around them but even at other believers who are not as committed as they are. These Christians don't need the gospel either. For them, Christian growth means more discipline and more commitment.
Then there is a third group. The baseline of this group includes more than the outward performance of disciplines, obedience, and ministry. These Christians also recognize the need to deal with sins of the heart like a critical spirit, pride, selfishness, envy, resentment, and anxiety. They see their inconsistency in having their quiet times, their failure to witness at every opportunity, and their frequent failures in dealing with sins of the heart. This group of Christians is far more likely to be plagued by a sense of guilt because group members have not met their own expectations. And because they think God's acceptance of them is based on their performance, they have little joy in their Christian lives. For them, life is like a treadmill on which they keep slipping farther and farther behind. This group needs the gospel, but they don't realize it is for them. I know, because I was in this group.
