He is the One through whom repentance and remission of sins is now granted. Repentance involves turning from sin to follow Christ. The follower must know how Christ wishes him to follow. He must be instructed, and when he wanders from the path of righteousness, he must be corrected of his error. The Scripture is used to fulfill these needs.
Scripture is to be used as the source of doctrine, discipline, and Christian practice.
Since Scripture is used in this manner, our goal must be to find what it teaches. When we understand what it teaches, we must put its teachings into practice. Many, even some with good intentions, have ignorantly misused Scripture. They have found things there that God never put there and have missed important things that are there. This has led to many doctrinal and practical controversies.
