1samuel 17;45 ‘’David replied to them’’ ‘’you came to me with sword, spear, javelin, but I came to you in the name of the Lord of Heavens Armies .The God of the armies of Israel, whom you have defied. Today I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild Animals. The whole world will know that there is a god in Israel. And everyone assembled here will know that the lord rescues his people, but not with Sword and Spear .This is the Lords battle , and he will you to us.’’
David was confident in God. He had faith that God will protect him and give him victory even though he was about to fight against an enemy much bigger than him. He did not fear. He faced his enemy and said exactly what was to happen ‘’the power of life and death lies in the tongue’’. As Christians living today we need to adopt a similar attitude.
