According to this scripture, how are our souls purified? By obeying the truth. Not just going through act, but “through the Spirit”. What truth do we obey? Sincerely loving the brethren. Since we do this, we can love one another more fervently. The word “fervent” used is the greek word ektenos. Which comes from the verb ektenes meaning to “stretch out the hand”. Love is not a mental affection or feeling but is an action. You can’t quietly love a person in your mind and not share it. Love is not just words. Feelings are fleeting, but true love extended has a lasting effect(fruit) in the one receiving it.
