What does it mean to come to God upright and sincere?

To come to God upright means to approach Him without hypocrisy and with a sincere acknowledgment of our need for His help. In 2 Samuel 22:26, God promises to show His character to those who come sincerely. This sincerity involves understanding our position as sinners deserving of judgment while also recognizing that only God can redeem us. Isaiah's vision in Isaiah 6 highlights this as he confesses his unworthiness upon seeing God's holiness. Being upright entails a genuine and honest heart that seeks God's face and recognizes that our righteousness is found solely in Him, as illustrated in Matthew 5:8, 'Blessed are the pure in heart, for they shall see God.'
