Galatians 3:26 (NKJV) For you are all sons of God through faith in Christ Jesus.
Hebrews 11:6 (MSG) It's impossible to please God apart from faith. And why? Because anyone who wants to approach God must believe both that he exists and that he cares enough to respond to those who seek him.
Ephesians 2:8 (NIV) For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God.
At the root of the Christian life lies belief in the invisible. The object of the Christian's faith is unseen reality. -- A. W. Tozer (1897-1963)
