Jesus said in John 6:63 that his words are SPIRIT and LIFE! Jesus is the word that became flesh and dwelt among us. (John 1:1, 14) Grace and peace is multiplied to us through the KNOWLEDGE of God, and of Jesus our Lord. (2 Peter 1:2) He has given us exceeding great and precious promises (2 Peter 1:4) and they are all available in his written word, the Bible.
What area of your life are you not seeing victory in? Do you know what God says about your situation? Do you know what Jesus has fulfilled on your behalf? In His word, there is an answer for every need that man will ever encounter.
