When we have carried you to your narrow bed, let us not have to hunt up stray words, and scraps of religion, in order to make out that you were a true believer. Let us not have to say in a hesitating way one to another, “I trust he is happy; he talked so nicely one day; and he seemed so pleased with a chapter in the Bible on another occasion; and he liked such a person, who is a good man.” Let us be able to speak decidedly as to your condition. Let us have some solid proof of your repentance, your faith, and your holiness, so that none shall be able for a moment to question your state.
Depend on it, without this, those you leave behind can feel no solid comfort about your soul. We may use the form of religion at your burial, and express charitable hopes. We may meet you at the churchyard gate, and say, “Blessed are the dead that die in the Lord.” But this will not alter your condition! If you die without conversion to God, without repentance, and without faith–your funeral will only be the funeral of a lost soul; you had better never have been born.
(Holiness, 228-229, emphasis added)
His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence, by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire.
For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love. For if these qualities are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ. For whoever lacks these qualities is so nearsighted that he is blind, having forgotten that he was cleansed from his former sins.
Therefore, brothers, be all the more diligent to confirm your calling and election, for if you practice these qualities you will never fall. For in this way there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ.
