Deuteronomy 31:8

It is the Lord who goes before you; He will be with you. He will not fail you or abandon you. Do not fear or be dismayed.  

In times of doubt, the Word of God is our reassurance. If we look toward the problem and do not speak the answer to that problem, our victory will never come. Only by the Word and the help of the Holy Spirit can we defeat the enemy and sin. Our job is to keep the faith and a clear understanding of our authority here on earth.
