Jonathan and the Lord's Work

I need to study the phrase "Perhaps the Lord will work for us." It is not a whim of fancy, this is a step of faith and of the Holy Spirit's prompting. Also the armor bearer's response is really good.

Jonathan said to the young man who carried his armor, "Come, let us go over to the garrison of these uncircumcised. It may be that the LORD will work for us, for nothing can hinder the LORD from saving by many or by few." And his armor-bearer said to him, "Do all that is in your heart. Do as you wish. Behold, I am with you heart and soul."
