There are too many believers, even churches as a whole, who teach according to their own interpretation of scripture, or what they think is in scripture. In Titus 2:1 Paul warns, You must teach what is in accord with sound doctrine. Unless we read the scriptures and know exactly what God is trying to tell us, then we are not to take liberties in interpretation and teaching. We should know what the Bible actually says before we give instruction on our individual opinions.
