The Importance of Knowing Your Christian Faith


The Importance of Knowing Your Christian Faith

Knowing what you believe—and why you believe it—is essential to living a confident, grounded Christian life. Faith was never meant to be vague, uncertain, or inherited without understanding. Scripture calls every believer to stand firm in truth, to grow in spiritual maturity, and to be ready to speak with clarity and conviction when questions arise. If we cannot explain what we believe, it becomes impossible to share our hope with others or to stand strong when our faith is challenged.

The Apostle Paul urged Timothy to take this responsibility seriously:

2 Timothy 4:2 (AMP)
“Preach the word [as an official messenger]; be ready when the time is right and even when it is not [keep your sense of urgency, whether the opportunity seems favorable or unfavorable, whether convenient or inconvenient, whether welcome or unwelcome]; correct [those who err in doctrine or behavior], warn [those who sin], exhort and encourage [those who are growing toward spiritual maturity], with inexhaustible patience and [faithful] teaching.”

This charge reminds us that knowing our faith is not optional—it equips us to teach, encourage, correct, and stand firm with patience and truth.

Peter echoes this same call to readiness:

1 Peter 3:15 (AMP)
“But in your hearts set Christ apart [as holy—acknowledging Him, giving Him first place in your lives] as Lord. Always be ready to give a [logical] defense to anyone who asks you to account for the hope and confident assurance [elicited by faith] that is within you, yet [do it] with gentleness and respect.”

A believer who understands their faith can speak with confidence, not arrogance; with gentleness, not fear; with clarity, not confusion. This kind of readiness strengthens our witness, deepens our walk with Christ, and helps us navigate a world filled with questions, doubts, and shifting beliefs.

This page is dedicated to helping Christians grow in understanding—so that your faith is not only heartfelt, but also well‑rooted, well‑reasoned, and joyfully lived out each day.

Understanding Apologetics: A Defense of Christian Faith

Apologetics is the study and practice of giving answers for the reasonableness and truth of the Christian faith.

  • Apologetics comes from the Greek apologia
    • means “to give a defense.”
      • it refers to a verbal defense or a reasoned statement or argument.
  • Apologetics is the branch of theology which deals with giving a defense of the Christian faith.

In 1 Peter 3:15, Christians are commanded to give an apologia to anyone who asks the reason for our hope.

  • 1 Peter 3:15 But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:

In a world where God’s Word often faces criticism both inside and outside the church, we should be ready to share the hope we have. Christianity is grounded in real history—actual people and events that truly happened. While we can counter arguments and explain the reasons for our faith, if we don’t point others to the life-changing gospel of Jesus Christ, we haven’t really defended the faith. Scripture reminds us to do this with meekness and fear, meaning we’re not here just to win arguments. Too often, Christian apologists can come across as loud, unkind, or prideful. We should proclaim the truth boldly, yet with self-control and the mindset of a messenger delivering the King’s message. We also act with reverent fear, knowing it’s only by God’s grace that we’ve been made ambassadors for Him, and that without the Holy Spirit’s work, our efforts alone can’t bring anyone to salvation. Above all, we must be careful not to misrepresent God by misusing the truth He’s entrusted to us.

These days, many Christians lack the discipline and discernment to defend their faith against “the fiery darts of the wicked one” (Ephesians 6:16). Over time, the church has become less effective at reaching those who are lost. While there are several reasons for this, a major one is that many believers have trouble explaining or defending their beliefs. As a result, Christianity is often viewed as a “blind faith,” and its followers are seen as uninformed or easily influenced.

Christianity isn’t a “blind faith” but is rooted in the God and His perfect, revealed Word. Hebrews 11:1 describes faith as “the substance of things hoped for, the evidence of things not seen.” So how can faith involve “evidence”? Because it’s anchored in real history—genuine people and events. While evidence can’t definitively prove the Bible’s truth, it can demonstrate that it supports Scripture. Viewed through the lens of God’s Word instead of human opinion, the evidence fits seamlessly with the Bible.

Throughout the New Testament the Early Leaders of the Church practiced apologetics. The authors of Scripture accurately recorded historical events, including the miracles of our Lord Jesus Christ and His Crucifixion and Resurrection.

  • Peter:
    • Wrote about the early followers of Christ:
      • 2 Peter 1:16 “For we did not follow cunningly devised fables when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of His majesty”.
      • The Apostle Peter also instructed his readers to
        • “sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear” (1 Peter 3:15).
  • Jude
    • Informed his readers about the importance of earnestly contending “for the faith which was once for all delivered to the saints” (Jude 3).
  • Paul
    • Practiced apologetics as he regularly went first to a town’s synagogue and “reasoned with them from the Scriptures, explaining and demonstrating that the Christ had to suffer and rise from the dead” (Acts 17:2, 18:4, emphasis added).
    • Paul reasoning with the religious leaders of the day does not sound like the actions of a man who had a blind faith.
    • Knew his faith was defensible.
      • He had encountered Christ on the road to Damascus (Acts 9:1–8)
      • He told the Corinthians that over 500 people had witnessed the resurrected Savior at the same time (1 Corinthians 15:6).
