Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
Not only must our heart be fixed and steadfast, it must also be confident. I have discovered that staying confident is a key to being positive in my mind and overall life.
Lucifer is constantly trying to introduce thoughts into my head to make me lose my confidence. Teh mind is the battlefield, and the devil lies to everyone through wrong thinking. The one thing that he's trying to steal all the time is our confidence.
The devil doesn't want us to have confidence in prayer. He doesn't want us to believe we can hear from our Father in Heaven. He discourages us concerning the call of God on our life. He wants us to go around feeling like a failure.
We need to confidently declare what the scriptures say about us, such as, "I am a divine son or daughter of Heavenly Father. I can do all things through Jesus Christ; who strengthens me. I am of divine worth." This means that we have Heavenly Father and the Lord on our side. They will help us along the way. They will speak truth to us.
We need to get up every morning prepared to keep the adversary beneath our feet.
