How do we know doctrine is important for Christians?

Doctrine, which means teaching, is foundational for the Christian faith as it instructs believers in understanding God's will and living according to His commands. In the sermon, it is noted that without good doctrine, believers are susceptible to false teachings and divisive behaviors. Paul wrote to Timothy to affirm the importance of sound doctrine as a means to combat falsehoods within the church and to guide believers in how to act in accordance with God's will. Thus, doctrine equips the church to respond rightly and brings unity among the members.
