Three words are often used to help describe how God works in and through His Word. Revelation is God revealing to us things not known before; Inspiration is God guiding those who recorded these details, and Illumination is God guiding us to understand. ILLUMINATION
To illuminate means to ‘shed-light’ upon something. Consider that as you read this passage –
1 Corinthians 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. 11 For what man knoweth the things of a man, save the spirit of man which is in him? Even so the things of God knoweth no man, but the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit which is of God; that we might know the things that are freely given to us of God. 13 Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
By His Spirit, God has revealed to mankind many great and wonderful things. By His Spirit, He has guided men to record these truths in exact detail. And by His Spirit, He guides us to understand them and to apply them to our lives.
Paul tells us that the Spirit often guides by ‘comparing spiritual things with spiritual.’ A teacher in Bible College once told me that the best commentary on the Bible is the Bible itself. By that he meant that scripture does not contradict itself, but rather it complements itself. So often when I am studying, a portion of a verse of scripture from another place in the Bible comes to my mind. Many times I do not know the whole verse, or even where it is located. As I begin to search for that phrase, the Spirit guides me to the verse and more often than not, takes my understanding to a deeper level.
