Romans 10:10

for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. ["The seat of faith," says Calvin, "is not in the brain, but in the heart. Yet I would not contend about the part of the body in which faith is located: but as the word heart is often taken for a serious and sincere feeling, I would say that faith is a firm and effectual confidence, and not a bare notion only." The belief must be such as to incite to love (1 Corinthians 13:1-2) and the obedience of faith (James 2:14-26). The faith of the heart introduces the sinner into that state of righteousness which in this present world reconciles him to God. The continual profession of that faith by word and deed works out his salvation, which ushers him into the glory of the world to come. Salvation relates to the life to come (Romans 13:11). When attained it delivers us from the dominion of the devil, which is the bondage of sin; from the power of death, which is the wages of sin, and from eternal torment, which is the punishment of sin. Such is salvation negatively defined, but only the redeemed know what it is positively, for flesh can neither inherit it (1 Corinthians 15:50) nor utter it-- 2 Corinthians 12:1-5]
