Deuteronomy 31:6

Be strong and of good courage, do not fear nor be afraid of them; for the Lord your God, He is the One who goes with you. He will not leave you nor forsake you. 

When we believe in God and believe what He says in His Word, we don’t believe according to our circumstances. Our faith, as we pray, according to God’s word, will move the mountain. God is by our side, leading us through and rebuking the devourer on our behalf. He will never leave us or forsake us as we believe and speak in faith.
