Relying on what God has done rather than on one’s own efforts. In the Old Testament, faith is rarely mentioned. The word trust is used frequently, and verbs like believe and rely are used to express the right attitude to God. The classic example is Abraham, whose faith was reckoned as righteousness (Gen. 15:6). At the heart of the Christian message is the story of the cross: Christ’s dying to bring salvation. Faith is an attitude of trust in which a believer receives God’s good gift of salvation (Acts 16:30-31) and lives in that awareness thereafter (Gal. 2:20; cf. Heb. 11:1).
