I find it interesting that none of the apostolic band, nor their delegates make any mention of the Great Commission in their writings to the churches or their associates?
If it was an Imperative (i.e. command) the Lord Jesus intended til the “end of time”, i.e. the world as we know it, why isn’t it repeated and/or reinforced?
One would think with the changing of the Covenantal order, especially, there would be a re-iteration making it clear the command was incumbent upon each succeeding generation.
But, such is not the case.
Jesus, a son of the Old Covenant (Gal. 4:4), gave the command to other sons of the Old Covenant, though now members of The Church and the New Covenant, while the Old Covenant was passing away (Hebrews 8:13).
These men, through the instrumentality of The Holy Spirit (John 16:13, 14), gave us the final inscripturated words of God, and none of them repeat this command, known as The Great Commission (Matt. 28:18-20).
Instead the focus is on “…equipping the saints for the work of ministry…” (Eph. 4:11) making certain there would be competent and equipped leadership to shepherd and continue the responsibility of the New Covenant church.
These men, I suggest, completed the task, fulfilling the Commission in that generation, and laid the groundwork for succeeding generations of saints in the unfolding aeons to advance the kingdom functioning as Salt, Light, and Leaven.
When one functions as Salt, Light, and Leaven, one has no control over the outcome, in terms of "cosmetic", i.e. what it (the result) will look like. One only has control over how one functions as "Salt", "Light", and "Leaven".
The outcome, result is in the hands of a Sovereign God who works all things after the counsel of his own will!
