Joshua "This is my command—be strong and courageous! Do not be afraid or discouraged. For the Lord your God is with you wherever you go.” Seven times He tells us to Be strong and do not fear. So why do we worry?
Philippians "Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
