Paul served as Timothy’s mentor. In fact, Paul referred to Timothy as his “son in the faith” (1 Timothy 1:2). As Timothy’s mentor, Paul gave Timothy truths with the intent that he would pass along those teachings to other believers. Though there are certainly variations of what should be taught, Paul laid out two foundational categories when he mentioned “words of faith and of good doctrine” (1 Timothy 4:6). Though specifics are given in the epistles of First and Second Timothy and Titus, every teaching should reflect the categories set forth by the apostle Paul. Even practical teaching ought to be based upon the words of God, as some teachings are good (2 Thessalonians 2:15), and some are bad (Matthew 15:9). Every teacher should teach with hopes of eventually learning from his students when they too become the teachers.
A yoke was an instrument used to help two animals work together when plowing. The Lord Jesus said that believers should take His yoke upon them (Matthew 11:29). In other words, the Lord was saying that we should serve with Him in our service to Him. In 1 Corinthians 3:9, we learn that “we are labourers together with God.” Fellowshipping with the Lord means walking with Him (1 John 1:6-7), and walking with Him means being in agreement with Him (Amos 3:3). Just as God desired to fellowship with Adam (Genesis 3:8) and Enoch (Genesis 5:22), He desires to have fellowship with us today. It is very important that we have fellowship with other like-minded believers, but even more important that we fellowship with the Lord.
