There are seventy weeks ordained for the holy city of God to become all that God wants it to be. The holy city in question is no longer the physical Jerusalem, but the New Jerusalem as we are told in Revelation 21:2. This New Jerusalem is the Lamb’s wife, which is the Church, as we are told in Revelation 21:9-10. The seventy weeks in Daniel are thus ordained for the Church to become all that God wants her to be, which is to be Most Holy and anointed with God’s glory.
Of these seventy weeks [seventy groups of seven years], the seventieth week, the final week, the final group of seven years, is when Messiah comes on earth to confirm the covenant and accomplish the following six things:  To finish the transgression,  To make an end of sins,  To make reconciliations for iniquity,  To bring in everlasting righteousness,  To seal up the vision and prophecy,  To anoint the most Holy.
True to it, at the end of the 69 groups of seven years [at the end of the appointed 483 years] Messiah came into the world, and was declared as “This is My beloved Son in whom I am well pleased.” [Matthew 3:17]. He began confirming the covenant, but as prophesied, He was cut off in the middle of the seven years [that is, after carrying out a three and half year ministry]. And during that first three and half years [through His preaching, His death and resurrection] He was able to accomplish the first three things in the covenant:  To finish the transgression,  To make an end of sins,  To make reconciliations for iniquity.
Now, He is about to return to complete the remaining three things in the remaining three and half years [the last half of His week]. But unlike the first time when He used a single body, this time God is preparing Him a body that is a church [many people operating in oneness]. And just as the first body He used was born of a virgin, so also this church that God is preparing for Him is made up of virgin-hearted believers gathered out from the backslidden church system. As that body was not born in the institutionalized hospitals, but in the humble manger, so also this church body that God is preparing for Him will not be produced in the institutionalized denominational church systems. It is not a church registered as an organization under any name or person. Rather, it is simple holy assemblies of God’s people all over the world, just as our Lord said in Matthew 18:20 “For where two or three are gathered together in My name, there am I in the midst of them”
God wants you to be part of this church body He is building for our Lord Jesus to come and:  To bring in everlasting righteousness,  To seal up the vision and prophecy,  To anoint the most Holy.
Please listen and be blessed. It is this body that is shown as the man child in Revelation 12, who is to carry out a ministry for 1260 days [which is three and half year]: the final three and half years of the seventy weeks. God bless you as you listen.
