Faith Alone... Grace Alone... Scripture Alone...
Faith Alone (Romans 3:28) - The Biblical teaching that a human being is justified--set free of all sin--by the atoning work of Jesus Christ. We are saved solely by faith, without the deeds of the Law.
Grace Alone (Ephesians 2:8-9) - The Biblical teaching that there is no other way to gain heaven except by the love God has for us, enough love that He sent His son Jesus to die in our stead.
Scripture Alone (2 Timothy 3:16) - The Biblical teaching that there is no other source for our understanding of God's grace and love except in the Bible, God's Word.
