Doubt is an experience everyone experiences. Even those with faith in the Lord struggle from time to me with doubt and say with the man in Mark 9:24, “I believe; help my unbelief!” Some people are significantly hindered by doubt, while others see it as a springboard to life. Others still see doubt as an obstacle to be overcome.
Classical humanism says that doubt, while uncomfortable, is vital for life. Rene Descartes once said, “If you would be a real seeker after truth, it is necessary that at least once in your life, you doubt, as far as possible, all things.” Similarly, the founder of Buddhism once said, “Doubt everything. Find your own light.” As Christians, if we take their advice, we would have to doubt what they said, which is contradictory. So instead of taking the advice of skeptics and false teachers, let’s examine what the Bible says.
Doubt can be defined as a lack of confidence or to consider something unlikely. We first see doubt in Genesis 3 when Satan tempted Eve. There, the Lord has given a command regarding not eating from the tree of the knowledge of good and evil and specified the consequences of disobedience. Satan introduced doubt into Eve’s mind when he asked, “Did God actually say, ‘You shall not eat of any tree in the garden’?” (Genesis 3:3).
Satan wanted Eve to lack confidence in the command of God. When Eve affirmed the command of God, including the consequences, Satan replied with a denial, which is a stronger statement of doubt, “You shall not die.” Doubt is a tool of Satan to make the people of God lack confidence in God’s Word and consider His judgment unlikely.
The blame for humanity’s sin does not fall on Satan but on mankind. When an angel of the Lord visited Zechariah, he was told he would have a son (Luke 1:11-17), but he doubted the word given to him. His response was one of doubt due to his age, and the angel responded, telling him he would be mute until the day God's promise was fulfilled (Luke 1:18-20). Zechariah doubted the ability of the Lord to overcome natural obstacles.
