Through Christ I can do all things through Christ which strengtheneth me" (Philippians 4:13). In weakness My grace is sufficient for you, for power is perfected in weakness" (2 Corinthians 12:9). From the Holy Spirit For God has not given us a spirit of fear and timidity, but of power, love, and self-discipline" (2 Timothy 1:7).
The Bible promotes a confidence rooted in God rather than self, often called "God-confidence," which comes from recognizing one's identity as a creation of God and trusting in His promises and strength. This perspective encourages humility, sobriety in self-judgment, and the understanding that one's strength is perfected through Christ in weakness. Key biblical themes include recognizing the power of the Holy Spirit within, finding strength in God's love, and having confidence in God's ability to complete the good work He has started in a person.
