But the person who obeys what His teaching requires, truly in this person love for God has been made complete. This is [another way] to be sure that we are in [fellowship with] Him:
And this is the [greatest] commandment [See Matt. 2:37-38] we have received from Him: [It requires] that the person who [claims to] love God should also love his brother.
[For] we [can] know that we have passed out of [the realm of spiritual] death and into [spiritual] life, because we [show] love for the brothers [and sisters]. The person who does not love [them] continues to be [spiritually] dead.
