This is how we know we love God’s children: when we love God and obey his commands.
This is my command: Love each other.
We can be sure that we know God if we obey his commands.
But if someone obeys God’s teaching, then in that person God’s love has truly reached its goal. This is how we can be sure we are living in God:
We know we have left death and have come into life because we love each other. Whoever does not love is still dead.
And God gave us this command: Those who love God must also love their brothers and sisters.
