What does the Bible say about confidence in God?

In Psalm 71:16, David expresses his confidence by stating, 'I will go in the strength of the Lord God.' This illustrates not only an assurance rooted in God's power but also the recognition that our capabilities are limited when compared to God's infinite might. Confidence in God means relying on Him, especially in times of struggle or adversity. David also highlights the importance of speaking of God's righteousness, pointing to an understanding that it is not by our works or merits that we stand justified, but solely through the righteousness of Jesus Christ. This principle of faith and reliance on God's strength is central to the believer's life, reflecting the essence of trusting in God's sovereignty and goodness.
