God puts an emphasis on learning sound doctrine and advises that sound doctrine is the believer's defense against false teachings. False teachers will use "good words and fair speeches to deceive" those who are poor in doctrine. Spiritually mature believers study the Word of God in a systematic and organized manner as a defense against false teachers who use the Word of God to deceive. Spiritually immature believers desparately need to be under the care of a pastor-teacher who goes deep into the Word of God week after week. These at risk believers need to be in the Word of God each day pumping bible doctrine into their souls. This is the means to spiritual maturity and the only defense against false teachers with their false doctrines. Spititually immature believers who hear feel good experiential messages Sunday after Sunday will be blown to and fro by the winds of false doctrines. Many of these winds are generated by the pulpits of the experiential preachers.
