2 To Timothy, a true son in the faith: Grace, mercy, and peace from God our Father and Jesus Christ our Lord. 3 As I urged you when I went into Macedonia—remain in Ephesus that you may charge some that they teach no other doctrine, 4 nor give heed to fables and endless genealogies, which cause disputes rather than godly edification which is in faith. 5 Now the purpose of the commandment is love from a pure heart,from a good conscience, and from sincere faith, 6 from which some, having strayed, have turned aside to idle talk, 7 desiring to be teachers of the law, understanding neither what they say nor the things which they affirm.–1 Timothy 1:2-7 (NLT)
Paul had left Timothy in Ephesus to continue teaching and mentoring the new converts there. Paul did not want the new converts to be swayed by those who taught false doctrines. These were the people who based their standing on religious traditions and their heritage. As Paul tells Timothy, we are to edify one another in our new faith. We do this by showing love, and having a pure heart that keeps us from straying from our belief in Jesus Christ. People desire to be teachers when they have need of instruction themselves. They become jealous of new leaders and try to sway people from the truth with their false doctrines. Be sure to check everything that you are taught and be sure it aligns with Scripture. Test every spirit to be sure it is coming from God and not satan.
