It’s important to note that simply “knowing” truth and doctrine is not what changes our heart or lifestyle. Jesus criticized the religious leaders of His day for being legalists. They were well-versed with the smallest details of the Old Testament writings, but they didn’t let that knowledge deep into their hearts to impact their lives. What matters most is whether the doctrine we profess to believe increases our love for God and our love for people. (Matthew 22:36-40)

On the flip side, we cannot love people or God correctly, if we do not have a proper understanding of biblical doctrine. We need to believe rightly in order to love effectively.
