Why is calling on the Lord important for Christians?

In Psalm 142, David cries out to the Lord in his desperate state, acknowledging that He is the only source of refuge and deliverance. This illustrates the importance of prayer and calling upon the Lord, especially when we feel weak and helpless. In moments of distress, recognizing God's sovereignty and our need for His assistance strengthens our faith. Additionally, calling on God's name is an act of obedience and trust, which is foundational to the Christian life, as affirmed in Romans 10:13, where it states that whoever calls on the name of the Lord shall be saved.
