Shalom,
Matthew 28:18-20:
18 Jesus approached and, breaking the silence, said to them, All authority (all power of rule) in heaven and on earth has been given to Me. 19 Go then and make disciples of all nations, baptizing them into the name of the Father and of the Son and of the Holy Spirit, 20 Teaching them to observe everything that I have commanded you, and behold, I am with you all the days (perpetually, uniformly, and on every occasion), to the [very] close and consummation of the age. Amen (so let it be).
The Amplified SO has this correct here! The Greek word for "teach" in verse 18 of the KJV is "matheeteuoo" and means: to disciple or make a disciple! The Greek word for "power" in verse 18 of the KJV is "exousia" and means: power of choice, liberty of doing as one pleases, power of rule or government! Jesus is saying that because HE has the authority, and we are IN HIM as believers (one with Him, equal heirs [Romans 8:17]), then WE can go in His power and authority and do these things He is commanding that we do! How are YOU doing with your obedience to these commands? We ALL can, and should, make it more of a priority. It IS His #1 priority! Amen!
