On our own we have zero capacity for faith in the true God revealed in the Bible. Therefore to grow in faith we need the God-given means of faith.
Have you ever wondered why Jesus admonished his disciples for their lack of faith in situations that would have tested even people of much faith?
The most surprising example of this was when a violent storm had nearly swamped the boat they were in, as Jesus slept peacefully on pillow. When the panicked disciples woke him, “he said to them, ‘Why are you afraid, O you of little faith?’ Then he rose and rebuked the winds and the sea, and there was a great calm” (Matthew 8:26).
We naturally think that it would take enormous faith not to be afraid in that situation. But Jesus faulted them for their fear, for their “little faith.” He did the same on other occasions. When the disciples could not cast out one particularly stubborn demon and the disciples asked him why, he pulled no punches, explaining, “Because of your little faith” (Matthew 17:20).
He said if they had faith only as small as a mustard seed they could move mountains. Yet the disciples did show faith when they left everything to follow him. So why did he fault them on other occasions?
The answer must be they had failed to rightly and fully employ the means of grace God had provided. They had neglected to use the ways God has given us all to grow in faith, and as a result they were men of little faith.
One of those means of growing in faith is reason.
1. Reason
Contrast the twelve disciples with the centurion—a gentile, no less—who rightly employed one of the means of faith, so much so that Jesus marveled. He asked Jesus to come and heal his servant and told him not to bother coming to his home but merely speak a word of command and the servant would be healed.
He explained, “For I too am a man under authority, with soldiers under me. And I say to one, ‘Go,’ and he goes, and to another, ‘Come,’ and he comes, and to my servant, ‘Do this,’ and he does it.” (Matthew 8:9).
Jesus remarked that he had never seen such great faith with anyone in Israel. On what did the centurion’s faith rest? On the foundation of reason. He had reasoned that if soldiers under his authority had to obey his words, then nature, including the disease in his servant’s body, had to obey the words of someone as manifestly authoritative as Jesus.
Although no one can come to saving faith in God by using unaided human wisdom and philosophy, God has ordained that human reason does play an important role in faith. That is why observing nature, for example, can lead to faith. It is obvious to any sane person without a sinful bias that a world of such amazing beauty, design, wisdom, and glory could not have come about except by an all-powerful and all-wise Creator. That is the right use of reason, and it leads to faith.
Let’s look at more God-given means to great faith.
2. The natural world
In the paragraph above we saw that reason can learn things about God from the natural world, and that is because it also is one of the most important means of faith.
Romans 1:19–20 says, “What can be known about God is plain to [unrighteous people], because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.”
The natural world shouts, There is a God! He has eternal power! He is divine!
Psalm 19:1–2 says, “The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge.”
Contemplating God’s role in the natural world can not only cause people to believe that God exists, it increases the faith of those who already believe. Ponder the complex design of the human body, for example, and you can grow in faith as you realize how great is the wisdom required to create and sustain life (see Psalm 139). And then you reason, If God can do that, he can do this.
3. Obedience
In large measure, faith is an act of obedience. We humbly choose to believe what God says, whether we understand it or not, whether we like it or not.
Romans 16:26 speaks of “the obedience of faith.”
Second Thessalonians 2:10 speaks of “those who are perishing, because they refused to love the truth and so be saved.” Such refusal is an act of the will. It is a choice. Such refusal is an act of intellectual disobedience.
Jesus told a group of people who raised questions about his credentials for teaching: “If anyone’s will is to do God’s will, he will know whether the teaching is from God or whether I am speaking on my own authority” (John 7:17).
In other words, the reason many people do not believe Jesus is they do not want to do God’s will. They attempt to hide their disobedient hearts by raising an unending list of questions and objections to this and that about God and the Bible, which they claim causes them not to believe. But Jesus says the real issue is they do not believe because they do not want to believe. They want to sin; they are in rebellion; and they rationalize it with unbelief.
Christians too can disobey intellectually
So how does this principle affect a sincere follower of Jesus? Even after we become Christians, pride and intellectual disobedience can be a problem. Thinking we know better than the Bible in certain issues is common even for Christians, especially when in those issues the Scriptures go against the grain of the wider culture. If we regularly find ourselves questioning, even challenging, the Bible, whether it is true and inerrant in all it maintains, we need to humble ourselves and accept the authority of Scripture over our minds and beliefs.
Faith is an act of obedience. I choose to believe what the Scripture says whether I understand it or not, whether I like it or not, whether our current culture approves or not. Why? Because Jesus always treated the written Scriptures as the inspired, inerrant, Word of God, and I believe that his life and ministry and resurrection from the dead validate his claim to be the Son of God. He knows what he is talking about.
I do not. I am a limited, erring human trying to figure out what is real. Proverbs 28:26 says, “Whoever trusts in his own mind is a fool.” I therefore have chosen to obey the one who I am convinced knows the truth. And so I obey him by believing what he says. Faith is a matter of obedience to one who has shown he knows what he is talking about.
The mindset I have just described would be disastrous if I have chosen to follow a person or philosophy that is false. That would be “drinking the Kool-Aid.” But having surveyed the field, there is no doubt in my mind that only one person and one book have stood the tests of time, reason, history, proven wisdom, science, conscience, and cogency concerning every aspect of life from family to finances to mental health. No one else holds a candle to the blazing light manifest in Jesus and the Bible.
It is the willingness to obey and believe that determines whether other means of faith given by God—such as nature and the Bible and reason and miracles—result in increased faith.
Next week we will continue looking at further God-given means of faith.
Jeremiah 9:23–24: “Thus says the LORD: ‘Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, but let him who boasts boast in this, that he understands and knows me, that I am the LORD who practices steadfast love, justice, and righteousness in the earth. For in these things I delight, declares the LORD.’” (ESV)
