Hi Nasher.Good to see you on Sunday! Do you have Vine's Expository Dictionary of New Testament Words? It is a must for anyone wanting to do serious word-study in the scriptures. Vine distinguishes the two words by saying:1. thelO: to will, to wish, implying volition and purpose, frequently a determination, it is most usually rendered to will. It is often translated 'to desire' in the 1881 Revised Version (American Standard Version)2. boulomai: to wish to will deliberately, expresses more strongly that thelO the deliberate exercise of the will it is also often ranslated 'to desire'in the 1881 Revised Version.I would say 'thelO' speaks more in our terms of 'willingness', while boulomai has more of the sense of a decision.This opens up an interesting issue. Does the Bible teach that 'the will' is a faculty of the soul? Teachers and preachers down the ages have concluded that it does. e.g. Luther: the Bondage of the Will, Edwards; the freedom of the will (by which he meant the same as Luther's 'bondage') However I can't find this usage in the NT. The Will is used of an authoratitive declaration of a king or of God, and is legitimate in the sense of a 'last will and testment', but the preachers' constant reference to 'your will must sumbit, be conquered, be broken' does not seem to square with the way the Bible uses the word. I am always anxious when psychological terms become the language of the people of God. The amount of writing and discussing that has gone into 'the human will' is amazing. What would be even more amazing is if there were no such thing! Suppose there is no such thing as 'volition' but just simple choices to be made when they are presented to us...More if you want it...
