The church, in order to be biblical and orthodox, she needs to be committed to the two "O's". What are these two "O's"?
Outward-moving in vision
It is not enough to be orthodox in doctrine, but the church must be outward-moving in her vision. Not static! Never static! It is possible to hold orthodox doctrine, so you think, and yet be unorthodox, because you are static and failing to show interest in reaching out to the lost. My two suggested "O's" are not perfect, but they get us all thinking, I hope.
As a younger Christian I read two terrific books by Iain Murray of the Banner of Truth. They were about Spurgeon being against Arminianism and also Hyper-Calvinism. These twin dangers are always around when there is any kind of Reformed recovery. We need to be aware of both. For example you can say that you tick all the boxes about Reformed doctrine and yet hold to sub-conscious hyper-Calvinism where due to a certain view of the doctrine of election that you do virtually nothing to make Christ known. Similarly, you may hold to particular redemption and yet be an Arminian in practice, in thinking that the kingdom of God will expand by the use of man-made methods. The dangers are very subtle for all of us.
However, the character of the Lord is outward-moving. The Lord our Father sent his only-begotten in His love and then the Holy Spirit was sent at Pentecost to spread the gospel and build up the church around the world. The Westminster Standards (the Confession along with the Larger and Shorter Catechisms) provide a biblically balanced theology. We should read the chapter in the confession on the Eternal Decree, but then pray the Lord's Prayer with the explanation of the Westminster Larger Catechism. Here is Question 191 to explain the second petition.
Q. 191. What do we pray for in the second petition?
A. In the second petition, (which is, Your kingdom come,) acknowledging ourselves and all mankind to be by nature under the dominion of sin and Satan, we pray, that the kingdom of sin and Satan may be destroyed, the gospel propagated throughout the world, the Jews called, the fullness of the Gentiles brought in; the church furnished with all gospel-officers and ordinances, purged from corruption, countenanced and maintained by the civil magistrate: that the ordinances of Christ may be purely dispensed, and made effectual to the converting of those that are yet in their sins, and the confirming, comforting, and building up of those that are already converted: that Christ would rule in our hearts here,18 and hasten the time of his second coming, and our reigning with him forever: and that he would be pleased so to exercise the kingdom of his power in all the world, as may best conduce to these ends.
We need to pray and work as the Lord spoke through Haggai in 2:4 "Work for I am with you declares the Lord of Hosts".
