Misguided and arrogant knowledge is spoken of in I Cor 8:1-12. This was a display of haughty disciples overriding the feelings of weak and untaught Christians regarding eating meats sacrificed to idols. True knowledge, on the other hand, is absolutely required. Jesus said, “You shall know the truth and the truth shall make you free” (Jn 8:32). Many times the Bible affirms the necessity of knowing the truth in order to be saved. It would be foolish to assert that preaching and teaching the true gospel of Christ is not necessary. No one can be saved in ignorance of the truth of Christ. We “purify our souls” by obeying the truth (2 Thess 1:8; 3:14; I Pet 1:22; 3:1; 4:17; Rom 10:16). We are to “worship in spirit and in truth” (Jn 4:24). Preaching and teaching the gospel “in love” (Eph 4:15) is all about sharing knowledge and understanding about Jesus. He commanded us to “Go and teach all nations…preach the good news to all creation” (Mt 28:18-20; Mk 16:15-16). These learners who “believe and are baptized will be saved.” They must also “continue in the apostles’ teaching” (Acts 2:42). Read your Bible daily. Ask the preacher for a study in your home.
