Many Christians are either woefully deficient in their knowledge of Scripture or noticeably devoid of any experience of God's power. The Lord never intended this for His people. We have all seen firsthand the joyless intellectual arrogance the absence of spiritual power can produce, as well as the fanatical emotional excess that comes from the lack of theological integrity.
The only reason integrity should be a burden to you is if you enjoy being dishonest.
This is the glory and miracle of grace, that God, through the Holy Spirit, is able to transform a stubborn, rebellious, and unbelieving will into a passionate, obedient, believing will without violating the integrity of the individual or diminishing the voluntary nature of one's decision to trust Christ for salvation.
Integrity... does not mean sinless, but it does describe a person who by God's grace "sin less."
