Christian Assurance and the Condition of the Heart

Christian assurance refers to a believer's confidence in their salvation and standing with God. This assurance is understood to be produced by faith [3], a fullness of faith that leaves no room for doubt [1]. It is confirmed by love and is an effect of righteousness [3]. The concept of assurance is closely tied to the condition and character of the heart, which is considered central to one's spiritual state [2].

The Bible describes the heart as the source from which the "issues of life" flow (Proverbs 4:23) [2]. God is depicted as trying, knowing, and searching the heart, understanding its thoughts, and influencing it [2]. The heart is also where God creates a new spirit (Psalm 51:10; Ezekiel 36:26) and prepares individuals for His purposes (1 Chronicles 29:18; Proverbs 16:1) [2]. For a renewed heart, its character is prepared to seek God, fixed on Him, joyful in Him, and perfect with Him [4]. Such a heart is described as upright, clean, pure, tender, single, sincere, honest, good, broken, contrite, and obedient [4]. It is also filled with God's law, awed by His word, and filled with His fear [4].

Assurance is not merely a mental assent but involves the heart. John Calvin explains that faith is not truly received when it "merely flutters in the brain," but when it has "taken deep root in the heart" [14]. This deep rooting in the heart provides an "invincible bulwark" against temptation [14]. The "full assurance of understanding" mentioned in Colossians 2:2 (KJV) refers to an unwavering conviction of biblical truth and a joyful steadfastness in one's grasp of that truth [1, 5]. Similarly, the "full assurance of faith" (Hebrews 10:22) signifies a complete trust in God [1].

The Westminster Confession of Faith states that while "hypocrites and other unregenerate men may vainly deceive themselves with false hopes," those who "truly believe in the Lord Jesus, and love him in sincerity, endeavoring to walk in all good conscience before him, may, in this life, be certainly assured that they are in the state of grace" [12]. This assurance allows believers to "rejoice in the hope of the glory of God" [12]. This confidence is not based on self-generated certainty but is a work of the Holy Spirit [13].

The role of the heart in assurance is further emphasized by the idea that love confirms assurance. The apostle John writes, "hereby we know that we are of the truth, and shall assure our hearts before him" (1 John 3:19, KJV), which commentators interpret as meaning that loving "in deed and in truth" provides this assurance [8]. If one's heart does not condemn them, they can have "confidence toward God" and a "sure answer to our prayers" [10].

However, the path to assurance is not always straightforward. Charles Hodge notes that many sincere believers can be "too introspective," looking "too exclusively within" for evidence of regeneration [11]. This introspection, he argues, "can never lead to the assurance of hope" because it is difficult to eliminate every doubt [11]. Instead, the grounds of assurance are found not so much within oneself, but in the objective truth of God's promises and the work of Christ [11]. The resurrection of Jesus, for instance, is presented as God's "assurance" or pledge that His revelation is true [1].

The character of a renewed heart, fixed on God, is a key indicator of assurance [4, 9]. This fixedness implies a trust in the Lord and a belief in salvation through Him, being rooted in God's love and built on Christ [9]. The love of God, described as sovereign, great, abiding, unfailing, and unalienable, is a foundational aspect of this assurance [6]. This divine love is manifested towards perishing sinners and His saints, providing a basis for confidence [6]. The compassion of Christ, particularly towards the weak in faith and the tempted, also serves as an encouragement for believers [7].

Easton's Bible Dictionary “Easton's Bible Dictionary: Assurance — The resurrection of Jesus (Acts 17:31) is the "assurance" (Gr. pistis, generally rendered "faith") or pledge God has given that his revelation is true and worthy of acceptance.

The two results of our being able to "assure our hearts before Him" (Jo1 3:19), and of "our heart condemning us not" (of insincerity as to the truth in general, and as to LOVE in particular) are, (1) confidence toward God; (2) a sure answer to our prayers.

The next thing necessary is, that what the mind has imbibed be transferred into the heart. The word is not received in faith when it merely flutters in the brain, but when it has taken deep root in the heart, and become an invincible bulwark to withstand and repel all the assaults of temptation.
