Why is confidence in God's promises important for Christians?

For Christians, having confidence in God's promises is essential for spiritual growth and resilience. This confidence allows us to approach God in prayer with assurance that He hears and responds to our petitions. As seen in Psalm 23, David's confidence enabled him to declare, 'I shall not want,' even amidst adversity. This same assurance leads us to trust God's providence, knowing that His goodness and mercy will follow us throughout our lives, encouraging us to remain steadfast in faith regardless of our circumstances.
