Add the Christian graces - II Peter 1:5-11
II Peter 1:5-11  And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;  And to knowledge temperance; and to 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 neither be 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 fall:  For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.

I Thessalonians 4:16 - 17 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:  Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
