What does the Bible say about approaching God in worship?

Scripture reveals that humans cannot approach God on their own terms or through their own works. In Isaiah 66:2, God declares that He looks to those who are humble and contrite in spirit. Mere outward acts of worship or adherence to rituals, such as prayers and creeds, cannot substitute for a heart that is fully aware of its need for God's mercy and grace. Jesus rebuked the Pharisees for their attempts to establish their own righteousness, and He emphasized that only those who recognize their moral bankruptcy can enter the Kingdom of Heaven (Matthew 21:31-32). Thus, it is vital for Christians to come before God with a heart of repentance, acknowledging their utter dependence on His grace.
