Faith is absolutely confident that the Lord God Almighty rules over all. Faith will not listen to doubt nor unbelief. The reason is simple, faith has heard from God. Faith is confident of the truth found in God's covenant word, the Bible. You see, "Faith comes by hearing, and hearing by the word of God" (Romans 10:17). Faith is confident, taking God at His word.
Doubt can never be confident. No matter what doubt hears, there is never any certain assurance. Not only that, but doubt thinks no one else can really know that God is real. Doubt says, "Maybe God is real and maybe He's not. There are times I've thought He is, then again I think He's not." Doubt thinks those who say they believe in God are really just playing a religious game.
Unbelief is dogmatic. Unbelief says, "There is no God. It is ignorant and uneducated people who say they believe in God. How stupid. Show me the evidence. If there is a God, I would know it and understand." Unbelief lifts himself up in pride, looking down on others who believe.
Faith is confidence in God. Faith is confident that God is at work. Faith is confidence in God our Father, and Jesus our Lord and Savior. Faith finds confidence in love, because "God is love" (1 John 4:8). Faith lives with joy, because faith has confidence in Christ. Faith is confidently confirmed by peace, because "the fruit of the Spirit is love, joy, peace" (Galatians 5:22).
