What does it mean to call upon the Lord in truth?

To call upon the Lord in truth is to understand and accept God’s nature, recognizing Him as the ultimate source of grace and truth. In John 14:6, Jesus declares that He is the way, the truth, and the life, emphasizing that genuine calling requires an acknowledgment of Christ's role in our salvation. This honesty before God must come from a heart that casts aside self-reliance and pride, embracing a posture of humility and repentance. Thus, true calling upon the Lord involves recognizing His greatness and our need for His mercy.
