One of the most important things for us to see is that God has but one eternal purpose that He is working toward. God is not double - minded, uncertain, or unstable, but He is very methodical, determined, and definite in everything that He does. God is not one to begin several projects and leave them all incomplete, but He has always completed that which He begins.
Since we have one God, its stands to reason that He has but one plan. Because God is one and there is no other God beside Him there can only be but one truth. God does not change His dealings with man but continually works all things after the counsel of His own will. God is not double-minded. He has but one will , one plan, one law, one goal ( Malachi 3:16).
If God were limited by human faculties of reason and sense perception as we are, He would be more like us in terms of accomplishment. But since God has infinite faculties (i,e., omniscience, omnipotence, omnipresence, immutability, omnisapience) He is able like no one else to declare the END from THE BEGINNING and see His plan come to fruition.
One thing that has hindered us from knowing God's eternal purpose is our limited perspective and frame of reference. We tend to look at God's eternal purpose and plan in terms of what we have seen happen in our time rather than what has happened for all time. We tend to look at God's plan by looking at the workings of God from the beginning to the end.
It is in the Church where all of God's intended purposes will come to realization. THE CHURCH IS GOD'S final instrument that He is using to bring about everything He intended. God will use the Church and His operation through the Church to bring us to completion, maturity, perfection and to the image we lost in Him (Ephesians 4:12-16, Colossians 3:10, Romans 8;28-30). GOD WILL USE THE CHURCH TO MEET HIS DESIRE FOR A BRIDE FOR HIS SON AND GOD WILL FIND IN THE CHURCH HIS SONSHIP IN THE EARTH.
God will use the Church to deal finally with Satan ( Matthew 16:18-19, Romans 16:20) God will use the church to rule and regin with Him for eternity. (Revelation 20:6). God's Church is the tool to bring mankind into the right relationship, in fellowship, Holiness and Godly's order.
