1 John 2:5 in the World English Bible
But God’s love has most certainly been perfected in whoever keeps his word. This is how we know that we are in him:
Context
4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
6 He that saith he abideth in him ought himself also so to walk, even as he walked.
