We know that we are children of God, and that the whole world lies in the power of the evil one (ponērō | πονηρῷ | dat sg masc).

I have written to you, my children, because you know the Father. I have written to you, fathers, because you know him who is from the beginning. I have written to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one (ponēron | πονηρόν | acc sg masc).

I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one (ponēron | πονηρόν | acc sg masc).

let us continue to draw near with a sincere heart in full assurance of faith, since our hearts have been sprinkled clean from a guilty (ponēras | πονηρᾶς | gen sg fem) conscience and our bodies washed with clean water.
