In the first several verses of second Peter, the apostle speaks of the great and precious promises that have been given to God's people whereby we can escape the snares of this world (v3-4). He then goes on to make numerous exhortations to righteous living and the benefits of obedience (v5-8). He then turns his attention to the consequences of those who disobey such admonitions...
"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 fall:" (II Peter 1:9-10)
