Spiritual Growth Objective
Cultivate a Christ-like heart and character that shapes our emotions and directs our will in ways marked by the fruit of the spirit.
Introduction to the Heart
Spiritual formation aims not only at the education of the mind but also the shaping of the heart. Why is the heart so important?
The heart is the center of human beings. The Bible uses the term “heart” to refer to the very core of a person. It is the source of our inner thoughts (Genesis 6:5), intentions (Genesis 8:21; cf. Hebrews 4:12), desires (Psalm 37:4), and the whole range of emotions including fear and courage (Psalm 27:14), anger (Psalm 55:21) and calm (Psalm 112:7), sorrow (Psalm 13:2) and joy (Psalm 13:5). We love God from the heart (Deuteronomy 6:5), and wisdom resides in the heart (Psalm 51:6; 90:12; Proverbs 2:10; 14:33). Thus, the heart reflects the person like a mirror (Proverbs 27:19), and God commands us to guard our hearts carefully for “from it flow the springs of life” (Proverbs 4:23).
A corrupt heart is the source of human sinfulness. Human acts of sin are not merely isolated events; rather, they are expressions of a deeper sinful condition of the heart. The heart is “deceitful above all things and desperately sick” (Jeremiah 17:9), and thus it is in our hearts that we devise wrongdoing (Psalm 58:2). When the spring becomes poisoned, the whole river that proceeds from that corrupt source is poisoned as well. Jesus describes the heart in this way when he identifies a corrupt heart as the source of human sins: “[W]hat comes out of the mouth proceeds from the heart, and this defiles a person. For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. These are what defile a person” (Matthew 15:18-20).
Spiritual transformation requires the renewal of the heart. We only truly honor God and fulfill his law and his purposes for us when we love God from the heart (Matthew 22:36-37). Since the diagnosis of our spiritual condition reveals a bad heart, the necessary prescription is a change of heart. God’s saving work in us consists of nothing less than a new heart made alive and responsive to God with love for God and a desire to obey God (Ezek. 11:19-20; 36:26-27; cf. John 3:5). Thus, David acknowledges that he needs God to change his heart in order to follow in God’s ways (Psalm 119:32), and God promised that he would write his law on the heart of his people (Jeremiah 31:33; Hebrews 8:10; 10:16). Paul likewise teaches that true salvation entails Christ dwelling in our hearts by faith (Ephesians 3:17) so that our hearts are inwardly enlightened (Ephesians 1:18) and transformed by the Spirit (Romans 2:29; cf. Deuteronomy 30:6). The result is that we can draw near to God with a cleansed heart, full of the assurance of faith (Hebrews 10:22) and love God and other people with a pure and sincere heart (Matthew 5:8; 1 Peter 1:22; 1 Timothy 1:5).
