Bottom line: No matter how much we may question or debate the unfolding of time, God is at all times completely in control of time.
Daniel's 70 Weeks vision is a very important prophecy. God has purpose and a plan for Israel and this prophecy lays it out. We see six things that God will accomplish for Israel. While much of prophecy has been fulfilled in terms of time, the purpose is yet to be fully realized. At the end of the 70 Weeks of Years, God will accomplish his plans and purposes for Israel. But, in the mean time, we're living in a gap between the 69th and 70th week. We're living in the "church age." God also has a purpose and a plan for the church. "Gap Time" is go time for the church to fulfill the Great Commission.
