Romans 5:1 (ESV) Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.
Philippians 3:9 (ESV) And be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith.
Hebrews 11:6 (ESV) And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.
There are only two kinds of religion in the world... You can list every "ism," every cult, every religion in the world under one category. They all say, "Do, do, do." Only Christianity says, "Done." Christ has done it all. —J. Vernon McGee, from The Best of Vernon McGee.
