From “Discipleship and Discipline” by William H. Hicks, copyright March, 2005:

“The Life of a Disciple

The fourth responsibility of a disciple of Christ is to be a teacher of God’s Word.   Teaching may be considered to be the core of the discipling transaction.  It is the “show me the money”, the payoff, of the discipling relationship between teacher and disciple.  The currency of this transaction is the Word of God coupled with the anointing of the Holy Spirit of God, the sharing experience between teacher and disciple and the ‘akou’ (gr.), “effectual hearing and doing” on the part of the disciple.  It is obvious from Paul’s letter that Timothy has the spiritual gift of teaching.  He is encouraged by Paul to cultivate and nurture his gift (I Timothy 4:13 – 16).

In II Timothy 2: 2, Paul tells us why disciples should teach: “And the things which you have heard from me in the presence of many witnesses, these entrust to faithful men, who will be able to teach others.”  And again, in II Timothy 4: 2, Paul writes: “preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience and instruction.”  So, we conclude that disciples must also be teachers.  This is consistent with the Great Commission, wherein we are called upon to “make disciples of all men, teaching them whatsoever I have commanded you”.”
