and in your knowledge, self-control, and in your self-control, steadfastness, and in your steadfastness, godliness,

and in your godliness, brotherly affection, and in your brotherly affection, [develop Christian] love [that is, learn to unselfishly seek the best for others and to do things for their benefit].
