Why is calling upon the Lord important in Christianity?

Calling upon the Lord is an essential aspect of the Christian faith, as it embodies the believer's dependence on God's mercy and grace. In the story of Bartimaeus, his desperate pleas for help illustrate the natural human response to recognizing one's own inability and sinfulness. When Bartimaeus calls out to Jesus, it is a manifestation of faith that acknowledges his condition and seeks divine intervention. Scriptures, such as Isaiah 55:6, encourage us to 'seek the Lord while He may be found,' reinforcing the idea that sincere prayer and cries for help are met with God's compassion and responsiveness. This act of calling not only signifies a personal relationship with God but also aligns us with His will and purpose for our lives.
