[44] These words of Paul, “I believed, and therefore have I spoken,” are taken from the 116th Psalm of David. That, therefore, oral confession proceeding from sincere faith conduces to salvation, Paul testifies with these words: “If thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.” Rom. 10:9,10. This faith exhibits also its outward fruits of love worthy of the faith; wherefore the believer, according to the teaching of the apostle Peter, must give all diligence to show forth from his faith, virtue, knowledge, temperance, patience, godliness, brotherly love, and charity; and walk in the Spirit, whose fruits, as love, joy, peace, long suffering, gentleness, goodness, faith, meekness, temperance, are seen on them outwardly. 2 Pet. 1:5–7; Gal. 5:16,22,23; 6:1; Eph. 5:9. By these good fruits, and by brotherly love, as external signs of the true faith, they are known as good trees, the salt of the earth, the light of the world, a light which is put on a candlestick, to give light unto all that are in the house, a city set on a hill which cannot be hid. And thus they let their good works so shine before men, that they, seeing them, may glorify God, the heavenly Father. Matt. 7:17,20; 12:35; 5:13–16. For, as children who in their appearance and deportment show forth their father’s form and qualities, are thereby judged and known to be the children of such parent, even so the believers, having, through the new birth, become partakers of the divine nature (inasmuch as they pattern after God in virtues), are thereby judged or known to be his children; and, in order that they might well express this image, they are abundantly admonished by Christ and his apostles in regard to it. So, for instance, with these words: “Be ye therefore perfect, even as your Father which is in heaven is perfect.” “But as he which hath called you is holy, so be ye holy in all manner of conversation;” “And every man ... purifieth himself, even as he is pure.” “Be ye therefore merciful, as your Father also is merciful.” Forgive one another, as God hath forgiven you. 2 Pet. 1:4; 1 Pet. 1:23; John 3:6; 1 John 4:7; 5:1; James 1:18; John 1:13; Rom. 8:16; Matt. 5:48; 1 Pet. 1:15; 1 John 3:3; Luke 6:36; Eph. 4:2; Col. 3:13.
