Summary: The word of God, spoken in faith in the Name of Jesus, has awesome power to overcome seemingly insurmountable obstacles.
Isaiah 55:10-11 ... so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it.
•• There is irresistible supernatural power in God's word; it will not return to Him empty.
•• God’s Word will accomplishHis desires and purposes. The King James Version descriptively says that the word of God will not return void to Him (Isaiah 55:11). In other words, it will get the job done!
•• The Word of God is powerful, because it is guaranteed by God to be effective.
Jeremiah 23:28-29 Let the one who has my word speak it faithfully ...  “Is not my word like fire,” declares the LORD, “and like a hammer that breaks a rock in pieces?”
•• Think of the Word of God as a hammer. Picture it.
•• This hammer can drive home a nail = positive results.
•• This hammer can break down obstacles = overcoming negatives.
•• “SPEAK [God's Word] faithfully” and (1) all kinds of positive things will begin to happen, and (2) all kinds of obstacles and opposition will begin to be broken.
•• Three times Jesus spoke to Satan: “It is WRITTEN!”, and Satan’s schemes were defeated. There is great power in the spoken word of God. Words have power when they are God's words spoken in faith through your lips. Thankfully, we don't have to guess what God's words are. Jesus didn't guess. He quoted the Scriptures (so should we), because the bible is the word of God.
John 11:43-44a When he had said this, Jesus called in a loud voice, “Lazarus, come out!”  The dead man came out...
•• In Genesis “God said, ‘Let there be...’ ” and light; sun, moon, and stars; animals, birds, and fish; and more came into being from God's spoken word of power.
•• Jesus said, "The words that I speak unto you, they are spirit, and they are life" (John 6:63). Speak His words, speak the Scriptures, because the word of God is life. Hebrews 4:12 (NASB) affirms this: "The word of God is living and active." God's words have life, they bring life, as did Jesus' spoken words to dead Lazarus.
•• Speak out God’s Word to your "Lazarus":
• “Devil, come out, because you are overcome by the blood of the Lamb.”
• “Cancer, leave this body, because by the wounds of Jesus this child of God was healed.”
• “Finances, come into line, because my God shall supply all my needs according to His riches in glory.”
John 8:51 I tell you the truth, if anyone keeps my word, he will never see death.
