What does it mean to have faith in God? Faith is to put your complete trust in someone. Just having intellectual assent is not enough. As James 2:19 tells us, even demons believe that God exists. What we believe with our mind must translate into the way we live our lives. As James 2:17 says, true belief will always turn into action, which is the way we live our lives.
True faith also means accepting all that God tells us about Himself—not just the bits we like. We must accept God as He is, not how we want Him to be. We also need to know the person we are putting our faith in. We need to understand who God is from what He’s shown us about Himself. The bible is God’s very own words about who He is and what He is like. Faith requires relationship to know, to trust, and to love God.
