Psalm 15:2 speaks of the man who "walketh uprightly, and worketh righteousness, and speaketh the truth in his heart." This verse defines the character of a godly person—one who walks in integrity and speaks truth from the heart. True righteousness is not merely about outward behavior but is deeply connected to the condition of the heart. When the heart is aligned with God, our actions and words naturally reflect His truth. To speak the truth in the heart means to live with sincerity and honesty, not only in public but in private as well. Integrity begins in the heart, and it overflows into all aspects of life, producing righteousness in our relationships with others and with God. This verse calls believers to examine the sincerity of their heart, ensuring that truth is deeply rooted within them. A righteous life is marked by an unwavering commitment to truth, both in words and actions.
