Guard Your Heart
Individually, we were created to serve God, but sin confused everything, tangling our hearts with pride, false idols, false securities, and false saviors all knotted together into one disordered mess from which we cannot free ourselves. Only by grace are we given eyes to see the depth of our complex hearts and two-faced motives, and only by grace do we find a Great Physician committed to untangling our disordered hearts. 
The heart is the inner core of a person. From it flows the thoughts, feelings, desires, and choices that define who we are and what we value. Jesus said, “For where your treasure is, there your heart will be also. (Matthew 6:21)
God promises to give everyone believing on the Lord Jesus Christ a new heart and a new spirit. By divine decree, God replaces the heart of stone with a heart of flesh, a new heart from heaven above placed within to love and live and walk in God’s holy ways. (Ezekiel 36:26; Psalm 51:10; John 3:1-10)
The call to guard the heart may sound cliché but is a daily admonition given for nurturing and protecting the new heart placed within (2 Corinthians 1:23). The call to guard the heart is to keep it untangled from the ways of the world and the deceitfulness of sin (Hebrews 3:13). It is a call to remain faithful to the Lord of Glory, the result of which is love, joy, and inward peace unmatched by the world. About the call to guard the heart the Apostle Paul penned the following words:
“Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.” (Philippians 4:6-7)
In flow with Paul’s admonition is the biblical theme adopted for this site, which is: “Guard your heart above all else, for it determines the course of your life.” (Proverbs 4:23 NLT)
Guard Your Heart is about walking apart from the ways of the world; it is about living free from the power of sin and from those who glory in their shame; it is about walking on the pathway of righteousness where the peace of God keeps our hearts and minds in Christ Jesus.

The Heart – Seat of Holy Affections
The Hebrew nouns leb and lebab (Strong’s 3820) are synonymous words, which speak of a person’s inner being and therefore are often translated heart. To the Hebrews, the heart was the seat of the affections, will, and mind. One’s emotions and understanding were centered in the heart (Proverbs 15: 13, 14), thus blurring the common dichotomy between mind and heart, intellect and emotions. Therefore to have a “clean heart” (Psalm 51: 10) is to have pure thoughts and desires.
To have a “hardened heart” (Exodus 4: 21) or a “heart of stone” (Ezekiel.36: 26) is to have a closed mind and deadened emotions. Early in human history, God identified the human heart as the center of rebellion, producing all kinds of evil (Genesis. 8: 21). For this reason, people found it impossible to obey God’s simple command to love Him “with all [their] heart” (Deuteronomy 6: 5). To remedy this deplorable situation, God determined to replace their “stony heart” with a “heart of flesh,” one which would love and obey its Creator (Ezekiel. 36: 26, 27).

The Spirit – Source of Holy Affections
About holiness Jonathan Edwards wrote,
“There is a holy breathing and panting after the Spirit of God to increase holiness which is as natural to a holy nature as breathing is to a living body. If you’ve been given a new nature, then the longing for holiness is natural in this world. The true believer loves God in the first place for the beauty of His holiness. Instead of being something separable from salvation, holiness is the very purpose of salvation. And once a person is renewed, a life of holiness is instantly begun and a transformation of nature is continued and carried on,” says Edwards, “to the end of life until it is brought to perfection in glory.”
