Hebrews 4:12,13

God Sees Us As We Are Some might think they can deceive God by pretending to be diligent. However, His powerful insight into the depths of man's soul is clearly seen in a full understanding of the nature of His word. So, the author next turned to a discussion of the word and the God who delivered it. He spoke of the "word of God" which Peter says is the incorruptible seed by which we are to be born (4:12; 1 Peter 1:23). It is the seed of the kingdom (Luke 8:11-15). By the hearing of it faith can be gained (Romans 10:17), without which one cannot be pleasing to God (Hebrews 11:6). If one will hear it, he can obtain blessing (Luke 11:28). The "word of God" was that which was delivered by Jesus and should dwell richly in the heart of the Christian (John 17:8; John 17:14; John 17:17; Colossians 3:16). By it we can find our salvation (John 5:24; Acts 20:32). It was this "word" that Timothy was to deliver (1 Timothy 4:5-6; 2 Timothy 4:1-5). However, the "word" is worthless to anyone who refuses to work the works it tells him to do (James 1:18-25). That word would be the good news that was carried to the entire world upon the instruction of Jesus (Matthew 28:18-20; Mark 16:15-16; Luke 24:47-49).

The writer said this word is alive and powerful, meaning that it carries a forceful, living message today. The word, which is the sword of the Spirit (Ephesians 6:17), is so sharp that it can divide the very "essence of man." That word is also able to discern, or judge, a man's very purpose in life. It can cause one to be seen as he really is since it reveals his very thoughts and feelings. It is really no wonder that this word has such powers, since God, who had that word written, is able to see all things, nothing being secret from him. This is the God with whose word we have to deal (Hebrews 4:13).
