The Pure in Heart – Matthew 5:8
Pastor Tan Thai · Aug 7, 2011
This sermon expounds the sixth Beatitude from the Sermon on the Mount: 'Blessed are the pure in heart, for they shall see God.' The pastor examines the biblical meaning of 'heart,' demonstrating that the human heart is inherently corrupt and only God truly knows and can renew it. Only through regeneration and the work of the Holy Spirit can believers live with a pure, sincere, and upward-directed heart.
The sermon opens by placing the sixth Beatitude from Matthew 5:8 within the context of the eight Beatitudes, emphasizing that it is the second one relating to relationships with others. The pastor defines 'heart' (kardia in Greek) not merely as a biological organ but as the center of the entire inner life of a person, encompassing intellect, will, and emotion. Jesus teaches in Matthew 12:34-35 and 15:19 that all actions, words, and attitudes flow from the heart.
The pastor highlights the contrast between the worldly view ('human nature is originally good') and the biblical teaching in Jeremiah 17:9 that the heart is deceitful above all things. Even when environment and education can modify outward behavior, the seed of sin remains within and no one can renew their own heart. The pastor acknowledges that believers do not deny the value of education or social reform, but recognize that good works are the result of salvation, not the means by which the heart is renewed.
The sermon then turns to God's promise in Ezekiel 36:26 to give His people a new heart and a new spirit. Through the story of Jesus meeting Nathanael (John 1:47) and the word of God in 1 Samuel 16:7, the pastor affirms that God sees the inside of a person's heart, not the outward appearance, and that Jesus needed no one to testify about people because He knew what was in every person (John 2:23-25).
The application section emphasizes that a pure heart does not mean sinlessness, but a heart that is open and willing for the Holy Spirit to work and transform it daily. A pure heart means consistency between inner thoughts and outward actions — no hypocrisy and no duplicity. The pastor warns against the Pharisaical danger of maintaining outward religious observance while harboring deceit and hatred within, referencing Titus 1:15 that to the defiled and unbelieving nothing is pure.
The sermon concludes that a new heart is an upward-directed heart, longing and planning for things that please God, with a straight and honest motive. This is the fruit of regeneration and the filling of the Holy Spirit in the believer's life — not the achievement of personal effort or social reform.
