One of the most aggressive things believers do is to wait on God. When He places us in circumstances where actions would be unwise or impossible, and wherein waiting is the only thing we can do, much is taking place that only our Lord can accomplish.
It doesn't feel this way, of course. It feels risky, and it seems that not taking matters into our own hands places us in the position of failure to deal with people and situations that require our involvement. The truth of the matter, however, is that when God stills our hand, He engages His own in ways that He alone can accomplish. Waiting on God therefore calls us to the active role of faith whereby we affirm that He is present and mightily at work in the situation. This is spiritual aggression of the highest order, and also prepares us for the time when we will be called to act.
We are to "fight the good fight of faith" (I Timothy 6:12). This involves both dynamic activity and quiet stillness, as led by the Holy Spirit. Both aspects of our arsenal do great damage to our spiritual enemies as we faithfully walk with God. He is never still in His ongoing working of "all things after the counsel of His own will" (Ephesians 1:11). Confident affirmation of this truth places us in our proper position of faith in times of waiting, and ensures that we do not add man made tools, as it were, to the building of altars that only God can construct (Exodus 20:25). It is not an easy way, and our own flesh, as well as our spiritual enemies, will tempt us to walk when we should be standing still. It is a necessary component, however, of fighting the good fight with the weapons that "are not carnal, but mighty through God to the pulling down of strongholds" (II Corinthians 10:4).
"Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which He will show to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever."
