All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work. 2 Timothy 3:16-17
What it means to be saved.
But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,  Persecutions, afflictions, which came unto me at Antioch, at Iconium, at Lystra; what persecutions I endured: but out of them all the Lord delivered me.  Yea, and all that will live godly in Christ Jesus shall suffer persecution.  But evil men and seducers shall wax worse and worse, deceiving, and being deceived.  But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;  And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. – (2 Timothy 3:10-15)
