6 Therefore my people shall know My name: therefore they shall know in that day that I am He that doth speak: behold, it is I.
7 How beautiful upon the mountains are the feet of Him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth!
Verse 6 describes His nature and perfections; His faithfulness in fulfilling His promises to them; His power in delivering them out of their bondage; and His justice in punishing their enemies.
In verse 7, people will see, when the people of God are delivered from the antichristian slavery and bondage, and when Babylon is fallen, that all the promises God has spoken are yea and amen; that Jesus Christ is the true and faithful witness; and that these are His true and faithful sayings, which He has spoken.
These prophecies, remember, are of the end times. They are about the Second Advent, when Jesus, Messiah, comes to rule and reign over the whole earth for 1000 years. Finally, after all the centuries of suffering, captivity, slavery, imprisonment and persecution, God’s people will see the fulfillment of His promises.
