“True believers may have the assurance of their salvation divers ways shaken, diminished, and intermitted; as, by negligence in preserving of it, by falling into some special sin which wounds the conscience and grieves the Spirit; by some sudden or vehement temptation, by God’s withdrawing the light of His countenance, and suffering even such as fear Him to walk in darkness and to have no light: yet are they never so utterly destitute of that seed of God, and life of faith, that love of Christ and the brethren, that sincerity of heart, and conscience of duty, out of which, by the operation of the Spirit, this assurance may, in due time, be revived; and by the which, in the mean time, they are supported from utter despair” (XVIII. 4).
The WCF rejects the Biblical truth that every true believer without exception by the Holy Spirit of God, continually cries Abba, Father:
“But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ” (Galatians 4:4-7).
Micah 7:7-9 (WCF “proof text”) speaks of a believer saying he will bear the indignation of the Lord for sinning against Him. In light of the other passages pertaining to the Spirit’s assuring witness, this must be talking about enduring indignation that is intended by God as a loving chastisement for his sin (Hebrews 12:5-11).
