Trust is the assured reliance on the character, ability, strength, or truth of someone or something.
Question: “What does the Bible say about trust?”
Answer: The words translated “trust” in the Bible literally mean “a bold, confident, sure security or action based on that security.” Trust is not exactly the same as faith, which is the gift of God (Ephesians 2:8-9). Rather, trusting is what we do because of the faith we have been given. Trusting is believing in the promises of God in all circumstances, even in those where the evidence seems to be to the contrary. Hebrews 11 talks about faith, which is accepting and believing the truth that God reveals about Himself, supremely in the person of His Son, the Lord Jesus Christ. Nevertheless, the practical consequence of faith in God is trust, which we prove by living out our full acceptance of God’s promises day by day. Furthermore, it is by this trust that we are promised peace: “You will keep in peace him whose mind is steadfast, because he trusts in you” (Isaiah 26:3). (Taken from Got questions.org.)
