What does the Bible say about keeping your heart?

The Bible instructs believers to keep their hearts with all diligence, as it is from the heart that all actions and motivations arise (Proverbs 4:23). This command underscores the necessity of ongoing self-examination to ensure that one’s inner life aligns with God’s will. We are reminded that God weighs the intentions of our hearts and will hold us accountable for what we nurture within (Psalm 51:6). The awareness of this reality should drive Christians to actively guard against sinful inclinations and pursue spiritual purity diligently, as a means of glorifying God.
