2 Pet 1:10.   Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall: 1 Thess 1:4-5.   Knowing, brethren beloved, your election of God. For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.
