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."

Oration, meditatio, tentatio

Luther asserted there were three practices necessary to become a biblical theologian:
Oration (prayer), meditatio (meditation), and tentatio (trials).

The passage that best demonstrates this in scripture in Psalm 119:

67 Before I was afflicted I went astray,
but now I keep your word.
68 You are good and do good;
teach me your statutes.
69 The insolent smear me with lies,
but with my whole heart I keep your precepts;
70their heart is unfeeling like fat,
but I delight in your law.
71It is good for me that I was afflicted,
that I might learn your statutes.
72 The law of your mouth is better to me
than thousands of gold and silver pieces
