Faithful = Trustworthy, Reliable, Believing all things that the bible says regardless of what all others say or what your 5 physical senses tell you.
 
Deuteronomy 7:6-9  Moses said:
           (6) Isreal, you are the chosen people of the Lord your God. There are many nations on this earth, but He chose only Isreal to be His very own.(7) You were the weakest of all nations,(8)but the Lord chose you because He had made a promise to your ancestors. Then with His mighty arm, He rescued you from the king of Egypt, who had made you his slaves.(9) You know that the Lord your God is the only true God. So love Him and obey His commands, and He will faithfully keep His agreement with you and your descendants for a thousand generations. (C.E.V.)
             In Deuteronomy 7:8 Moses says that the Lord chose Isreal because He loved Isreal and had made a promise with there ancestors. God even rescued them from the king of Egypt when they were slaves.
             *NOTE: It says God made there ancestors a promise and God is helping Isreal because of that promise. See God is faithful. You see the definition of faithfulness is Trustworthy, Reliable, and Believing. God is all three (3) of these things. He's obviously trustworthy because even after many years God kept His promise to Isreal.
                He is reliable because through the book of Joshua God helped them conquer all the promised land. He is believing  because in Joshua 6:18-19 God tells Joshua that everything in Jericho belonged to Him and that if anyone were to take and keep anything from Jericho the Lord would destroy Isrealand the individual who had taken the items would be at fault and held accountable for that. In Joshua 7 Isreal tried to defeat the town of Ai and Isreal ended up taking a loss of 36 troops. God told Joshua that someone had kept things from Jericho that were to be the Lords. See the reason that I say that God is believable is because He said that He would destroy Isreal if someone kept His belongings and He kept up to His word Isreal failed against Ai.
              
                 You know today I challenge you to take God up on His word and walk in faith because faith without works is dead. Let God take care of your every needs Cast your cares upon Him.
