The F.O.G*

[14] We know we've crossed over from death to life because we love our fellow believers. Anyone who doesn't love remains in death's grip - it's like having a spiritual EKG that reveals our true heart condition.We know that we have passed from spiritual death into the spiritual life of God because we truly love fellow believers. Anyone who does not love sacrificially remains spiritually dead.

The F.O.G Paraphrase

we—we have known that we have passed out of the death to the life, because we love the brethren; he who is not loving the brother doth remain in the death.
