Memory Problems?

One of the things that irks me the most is that I have given back ground that I had previously won victory in. A passage that has urged me to be diligent this time comes from the second epistle written by Peter:

And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; and to knowledge temperance; and the temperance patience; and to patience godliness; and to godliness brotherly kindness; and to brotherly kindness charity. For if these things be in you and abound, they make you that ye shall be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins. Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fail. -- II Peter 1:5-10

Did you catch that? It says right there in the scriptures that if we do not give all diligence to continue to add to our faith, that we will be blind and will forget that we were purged from our old sins. We will begin to doubt our position in grace if we do not diligently seek after God to add to our faith. Notice, it doesn't say that we will no longer be purged; it simply says that we will forget that we were purged. So, let us be diligent, lest we forget we were purged and stumble around in the wretched darkness of fear and doubt.
