How do we distinguish the promptings of the Spirit of grace in His guiding and governing of our lives from the delusions of the spirit of the world and of our own sinful heart? This is a hugely important question if we are to be calm and confident that the spirit with whom we are communing really is the Holy Spirit.
John Owen suggests four ways in which the Spirit and the serpent are to be distinguished:
The leading of the Spirit, he says, is regular, that is, according to the regulum: the rule of Scripture. The Spirit does not work in us to give us a new rule of life, but to help us understand and apply the rule contained in Scripture. Thus, the fundamental question to ask about any guidance will be: Is this course of action consistent with the Word of God?
The commands of the Spirit are not grievous. They are in harmony with the Word, and the Word is in harmony with the believer as new creation. The Christian believer consciously submitted to the Word will find pleasure in obeying that Word, even if the Lord’s way for us is marked by struggle, pain, and sorrow. Christ’s yoke fits well; His burden never crushes the spirit. (Matthew 11:28-30)
The “motions” of the Spirit are orderly. Just as God’s covenant is ordered in all things and secure, (2 Samuel 23:5) so the promised gift of that covenant, the indwelling Spirit, is orderly in the way in which He deals with us. Restlessness is not a mark of communion with the Spirit but of the activity of the evil one. Perhaps Owen had particular members of his congregations in mind when he wrote:
We see some poor souls to be in such bondage as to be hurried up and down, in the matter of duties at the pleasure of Satan. They must run from one to another, and commonly neglect that which they should do. When they are at prayer, then they should be at the work of their calling; and when they are at their calling, they are tempted for not laying all aside and running to prayer. Believers know that this is not from the Spirit of God, which makes “every thing beautiful in its season.”
The “motions,” or promptings of the Spirit, Owen says, always tend to glorify God according to His Word. He brings Jesus’ teaching into our memories; He glorifies the Savior; He pours into our hearts a profound sense of the love of God for us.
How, then, does the Spirit act on the believer? The Spirit comes to us as an earnest, a pledge, a down payment on final redemption. He is here and now the foretaste of future glory. But His presence is also an indication of the incompleteness of our present spiritual experience.
Owen here writes in sharp contrast to those who spoke of release from the influence of indwelling sin and struggle through the liberty of the Spirit. Precisely because He is the firstfruits and not yet the final harvest, there is a sense in which the indwelling of the Spirit is the cause of the believer’s groaning: “We ourselves who have the firstfruits of the Spirit groan inwardly as we wait eagerly for our adoption as sons, the redemption of our bodies.” (Romans 8:23) The presence of the Spirit brings us already a foretaste of future glory, but also, simultaneously, creates within us a sense of the incompleteness of our present spiritual experience. This, for Owen, is how communion with the Spirit—understood biblically—brings joy into the life of the believer and yet a deep sense that the fullness of joy is not yet.
