2 Peter 1:8-11

For if these things are yours and abound, they make you to be not idle nor unfruitful unto the knowledge of our Lord Jesus Christ. For he that lacketh these things is blind, seeing only what is near, having forgotten the cleansing from his old sins. Wherefore, brethren, give the more diligence to make your calling and election sure: for if ye do these things, ye shall never stumble: for thus shall be richly supplied unto you the entrance into the eternal kingdom of our Lord and Saviour Jesus Christ.
