2Pe 1:7 to godliness brotherly kindness, and to brotherly kindness love.
In our godliness, as the Apostle says, we must add to it brotherly kindness. It is the essential element of our godliness. Brotherly kindness is an intentional good will towards the saints. The natural affection and brotherly kindness are to be sanctified by godliness. To pursue godliness will indeed put us in the company of our fellow Christians. The duty we all have is to extend the kindness and love we have received from Christ to our fellow brothers. Grace unites man to God, and man to man.
Brotherly kindness is sweetened by the power of love. Paul in 1Cor 14:1 states that the priority of a believer is to pursue (go after) love. In the same breathe he mentions spiritual gifts as secondary to be desired and asked for (not pursued). Love is the first and chief aim, seeing that it is “the greatest” (1Co 13:13). The true test of our testimony is not in our knowledge of the word or in possessing of the gifts of the spirit, it is but in the application of the word. Joh 13:35 “By this all will know that you are My disciples, if you have love for one another.” Faith must be practical.
