Bonnie--if works are connected to inheriting the Kingdom of God--then faith alone theology is false--regardless of what "function" you believe it has.
Galatians 5:19-21---King James Version
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Galatians 6:7-9---King James Version
7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
Faith alone theology demands all works to be exclusive in inheriting eternal life--period.
Luke 6:46---King James Version
46 And why call ye me, Lord, Lord, and do not the things which I say?
