What is True Faith?

August 25, 2026

One of the most important verses in the entire Bible is found in Genesis 15, “Then he believed in the Lord; and He reckoned it to him as righteousness” (Genesis 15:6 NASB95). These words were spoken about Abraham on the night that God took him outside, told him to look up at the stars of heaven, and said to him, “So shall your descendants be” (Genesis 15:5). Abraham believed God’s promise, and because he believed, God credited righteousness to Abraham. He was declared righteous—justified—in that moment.

This verse is quoted on multiple occasions in the New Testament which tells us that it is of great significance. And it holds an incredibly important promise for you and I today. It tells us that we too can be counted as righteous in the eyes of God if we will believe in God’s promises—particularly, His promise of forgiveness and eternal life through the death and resurrection of Jesus Christ. We, like Abraham, can be justified by faith (Romans 4:3-5, 22-24).

But what is faith? Is it merely a profession of belief in God?  Is it intellectual agreement with the major tenets of Christianity?

This is the question that James sets before us in James chapter 2. What is true faith? James is clear that it is more than words spoken. It is more than holding to orthodox beliefs. Real faith is a faith which responds to the word of God in obedience. James points to Abraham as an example of this kind of faith. James writes, “Was not Abraham our father justified by works when he offered up Isaac his son on the altar?” (James 2:21). It is critical to understand that Abraham offered up Isaac some 30 years after God justified Abraham back in Genesis 15. So which is it? Was Abraham justified when he looked up at the stars and believed God’s promise, or was he justified when he offered up Isaac?

It is in this question that we see the correlation between what Paul and James say about faith and justification. They are using the term “justified” in different—but complementary—ways. Abraham was, in fact, justified by God when he believed in God’s promise. And he was, in fact, justified 30 years later when he offered his son. In the former case, justification means that Abraham was declared righteous by God. In the latter case, justification means something like “vindicated” or “proven to be real.” Abraham was justified in the sense that his faith was proven to be more than just words. The work that he did in offering Isaac completed his faith and fulfilled the earlier words spoken about Abraham (James 2:22-23).

So what is real, saving faith? Paul and James agree. It is trust in God that is demonstrated in action and obedience. Paul speaks of how a sinner is made right with God through faith; James speaks of how that faith is shown to be real.

What about you and me?  Is your faith just words spoken or is it real? Like Abraham, let us show the genuineness of our faith through obedience to our Lord.

What is Faith?

February 27, 2024

Since the wages of sin is death, it is very important to know how to receive the free gift which is eternal life. Paul begins Romans with this great statement of his theme: “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek” (Romans 1:16, ESV). The gospel is clearly offered to all, but faith is a condition for receiving the gift. If the gospel was not offered to all, Paul could not claim, “For God shows no partiality” (Romans 2:11, ESV).

So what is faith? In English, we speak of belief, faith, and trust. Greek had one word group that covered that range of meaning. Belief or faith includes intellectual assent. Intellectual assent can especially be seen in phrases like “believe that”.

“And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.” (Hebrews 11:6, ESV)

“You believe that God is one; you do well. Even the demons believe- and shudder!” (James 2:19, ESV)

The last quote clearly indicates that intellectual assent is not enough. The Bible also speaks of faith in the sense of trust. This can be seen in phrases that say believing in or on someone (e.g., “the righteousness of God through faith in Jesus Christ for all who believe” Romans 3:22, ESV).

Paul is also clear about how we acquire faith. “So faith comes from hearing, and hearing through the word of Christ” (Romans 10:17, ESV). Faith is a response to testimony (see also John 20:30-31). Those who would argue from Ephesians 2:8 that faith is a gift have missed the point. The “this” in the passage points back to the whole process of salvation by grace conditioned by faith as clearly seen in the Greek grammar of the passage.

In Romans, Paul contrasts faith/trust with works/merit. We are either going to earn salvation by perfect law keeping, or we are going to have to trust in the saving work done for us by Christ. But perfect law keeping is only hypothetically possible since we can’t live it perfectly. “For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin” (Romans 3:20, ESV). We must trust what Jesus has done for us.

As Paul explains this faith/trust, it does not exclude but includes repentance (Romans 2:4). It does not exclude but includes baptism (Romans 6:3). It does not exclude but includes confession (Romans 10:9). Given the argument of the letter, these things that Paul includes cannot be meritorious works but must be expressions of trust/faith. Finally, also note that for Paul faith/trust leads to obedience (Romans 1:5, 6:17, 16:26). Obedience is produced by faith. The person who trusts God will want to obey God.
