Our confidence comes from our relationship with Christ. Putting our trust in God and His revealed Word, our lives take on a new stability, focus and poise, confidence in God's Word and character.
"...being confident of this, that He who began a good work in you will carry it on to completion until the day of Christ Jesus." Philippians 1:6
"The wicked man flees though no one pursues, but the righteous are as bold as a lion."
