“For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge;6 and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness;7 and to godliness, mutual affection; and to mutual affection, love.” (II Peter 1:5-7)
The Christian life requires you to practice each of the highlighted qualities above:
Faith: in order to be a Christian and to truly love others you must believe in God who created you, repent of your sins, and confess that Jesus the Son of God has died for your sins and been raised from the dead.
Goodness: Those who have been saved from their sins must do good works. If you do not do good works you are probably not be a true believer, but an imposter.
Knowledge: If you truly love God you will want to know more about Him. Therefore you will read your Bible and ask question of other Christians. The Holy Spirit which is inside you will help you learn.
Self-control: Now that you know what is wrong you must keep yourself from doing it. You must resist fleshly sinful, fleshly urges because you know they are wrong.
Perserverance: Now that you have started well, you need to keep living a holy life until you die, to show that the change inside you is genuine.
Godliness: Now that you have learned about God, and he has given you self control, you are able to act with the same love and goodness that God possesses. You must behave as a true child of God.
Mutual Affection: You need to care for others more than you care for yourself.
Love: It’s all about love. You need to love God, and love your neighbor as yourself. You are even commanded to love your enemies.
