If you have little to no faith it may be because you're not spending time hearing the Word of God.
Better yet, when you read the word of God, you have the opportunity to hear directly from Him.
You encounter His voice and His presence from reading His Word.
The more time you spend with Him, the less you believe the report of the enemy.
Have faith. Listen to the Word of God.
So then faith cometh by hearing, and hearing by the word of God.
Romans 10:17 KJV
