We Christians are destined to be kings in the Lord’s kingdom….It is impossible to be a king without…maturity. Even if the Lord would want to enthrone as a king someone who is not mature, that person would realize that he is not able to exercise the kingship. This indicates that even we ourselves know that we need to grow to maturity in order to be kings.
According to Peter’s word in 2 Peter 1:5-11, to grow to maturity is to develop what we have already received. We have been allotted the wonderful like precious faith, and this faith is an all-inclusive seed. All the divine riches are in this seed, but we must be diligent to develop them into virtue. Then we need to develop in our virtue knowledge; in knowledge, self-control; in self-control, endurance; in endurance, godliness; in godliness, brotherly love; and in brotherly love, love. By developing these virtues we grow, and eventually we shall reach maturity. As a result, we shall be full of Christ, and, in Paul’s words, we shall arrive at the measure of the stature of the fullness of Christ (Ephesians 4:13). Then we shall be qualified and equipped to be kings in the coming kingdom. (Life-Study of 2 Peter, ch. 7)
