There are two fundamental ways of living in this world: by sight or by faith. The majority of people live according to what they can see and what appears desirable in the present moment. In contrast, Christians are called to live by faith. Faith enables believers to perceive what is true even when circumstances appear to suggest otherwise. Therefore, an important question must be asked: Is our faith active and living, or is it merely theoretical?

An active and living faith gave Rahab a new identity before God. Rahab was a harlot, a woman considered among the lowest members of society, yet her sinful life was transformed through faith. Prostitution was a deeply stigmatized occupation—morally, socially, and religiously—and the Bible clearly condemns it. Nevertheless, this was only Rahab’s former identity. In a similar way, every Christian once possessed an identity marked by sin before God. Since the Fall, all people are born into sin; “for all have sinned and fall short of the glory of God” (Rom. 3:23). Human nature is corrupted in mind, heart, and will. Left to ourselves, we choose sin rather than God. In this sense, humanity stands before the holy God as spiritual harlots. Only through faith in Jesus Christ can we receive a new identity.

Within this new identity are several characteristics that marked Rahab and likewise mark every Christian.

First, Christians become children of God. Their identity is no longer defined by sin, shame, or worldly status. Rahab herself was forgiven and accepted by God. Regardless of one’s past, believers are not ultimately defined by their former sins but are clothed with the righteousness of Christ.

Second, Christians become new creations. As Paul writes, “If anyone is in Christ, he is a new creation; the old has passed away; behold, the new has come” (2 Cor. 5:17). Although remnants of the old life remain, a genuine transformation has occurred in both nature and direction. This new life is the work of the Holy Spirit.

Third, believers abide in the Lord and become members of Christ’s body. Their lives are marked by ongoing repentance and submission to God’s will.

Fourth, Christians are called to be ambassadors of reconciliation. As stated in 2 Corinthians 5:18–20, believers are sent by God to proclaim the gospel so that sinners may be reconciled to Him.

Finally, believers are coheirs with Christ. As Romans 8:17 teaches, Christians share in Christ’s inheritance and receive the spiritual blessings of God’s kingdom. Their true citizenship is in heaven (Phil. 3:20), which ultimately defines their identity and destiny.

Active and living faith also saves. By faith, Rahab “did not perish with those who were disobedient” (Heb. 11:31). Saving faith rescues people from sin, death, judgment, and eternal separation from God. It produces a personal trust in the Lord Jesus Christ and acknowledges humanity’s desperate need for salvation. Such faith inevitably results in obedience and perseverance, for “He who began a good work in you will bring it to completion” (Phil. 1:6). Although the Christian life includes many trials and struggles, its overall trajectory is directed toward God through steadfast trust in Him. Saving faith is not merely intellectual or theoretical—it manifests itself in real and observable ways.

Furthermore, active and living faith results in obedience. Obedience is the clearest evidence that genuine faith is alive. While obedience itself does not save, true salvation inevitably produces the fruit of obedience, just as a living tree naturally bears fruit. Rahab demonstrated this reality when she welcomed the Israelite spies. At the time, her actions constituted treason against her own city. Had she been discovered, both she and her family could have faced severe punishment or death. Nevertheless, Rahab acted without hesitation because her living faith placed God’s will above all other concerns.

Choosing obedience often involves risk. However, active faith depends on the living God rather than on human security. Obedience to God must be practiced in real life, not merely discussed in theory. Because faith is personal and genuine, obedience must also be concrete and visible. Each day, believers must be prepared to obey whatever God requires of them. Even in discipleship, a true follower of Christ prioritizes God’s will, wisely applies His Word, and remains available to guide others in the faith.

Scripture warns that “faith by itself, if it does not have works, is dead” (James 2:17). The Christian life can therefore be described simply as a life of obedience. Practical obedience often requires taking risks for the sake of God’s will and glory. Rahab’s example invites us to examine our own lives. Do we maintain comfort zones that prevent us from fully obeying God’s Word?

Comfort zones in the Christian life may appear in several forms. A believer may choose to live spiritually unchanged because it feels safe and requires little growth. Others maintain predictable spiritual routines that never challenge their faith. Some practice controlled obedience—obedience that carries little or no personal cost. In essence, such attitudes say, “I want Christ, but without difficulty or sacrifice.”

These comfort zones are spiritually dangerous because they produce lukewarm faith. In the book of Revelation, Christ warns against such complacency: “Because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth… Behold, I stand at the door and knock” (Rev. 3:16, 20). Lukewarmness can deceive people into believing they are saved when their faith is actually lifeless. It does not produce genuine repentance, because the Holy Spirit is not actively convicting the heart. Such individuals often lack desire for prayer or for the Word of God, and their hearts gradually grow hardened. What remains is merely the outward appearance of religion without true devotion to Christ.

In contrast, those who possess active and living faith genuinely love Christ and hunger for His Word. If this hunger is absent, believers should honestly examine themselves. When was the last time we obeyed God in a way that cost us something meaningful? If our faith is never tested or stretched, we may be living safely rather than faithfully. Christians must guard against the dangers of a comfortable, culturally shaped faith that produces spiritual lukewarmness.

Just as Rahab would have perished in her sin without faith, we too would remain condemned if we continued in our depravity. Yet through living and active faith, we can depend on the Lord in repentance and obedience. Such a life moves beyond comfort zones and becomes centered on the gospel. As long as we live, we must not waste the grace God has given us. Instead, we should respond with gratitude for His mercy by continually repenting and striving to live faithfully before Him.
