Short answer
Faith is confident trust in God — believing what He has revealed and relying on His promises. Saving faith is the wholehearted reliance on Jesus Christ alone, based on His person and finished work, that brings forgiveness, new life, and assurance of salvation.
What Scripture says
"Now faith is the assurance of things hoped for, the conviction of things not seen."
"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."
"So faith comes from hearing, and hearing through the word of Christ."
"For by grace you have been saved through faith. And this is not your own doing; it is the gift of God."
Going deeper
Faith is not blind. Biblical faith is grounded in the character of God and the truth of His Word. It is the kind of trust you have in a doctor who has shown her skill, or a friend who has proved his love — only deeper, because God is perfectly faithful. Faith looks at Jesus, sees who He is and what He has done, and rests there.
Theologians have long said true faith includes three things: knowledge (understanding the gospel), assent (agreeing it is true), and trust (personally relying on Christ). You can know about Jesus and even agree the gospel is true without ever actually trusting Him. Saving faith is more than intellectual — it is a transfer of trust from self to Christ.
Faith is not the cause of our salvation; Jesus is. Faith is the empty hand that receives the gift. Even our ability to believe is a gift from God (Ephesians 2:8). This means salvation is entirely of grace, and our boasting is in Christ, not in our believing.
Faith is also not a one-time event but a lifelong walk. The Christian life begins by faith, grows by faith, and ends by faith. We trust Christ for forgiveness today, for grace tomorrow, and for resurrection in the end. Doubts may come; the answer is always to look again at Jesus.
