1 John 4:19-21
19 We love him, because he first loved us.
20 If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?
21 And this commandment have we from him, That he who loveth God love his brother also.

Here is a foundational truth of the issue of loving OneAnother.

Remember, we as Believers love because He first loved us.
It is the love of the Lord in which we choose to live.

Therefore, if someone claims to love God, yet they hate their brother, then they are a liar.

Simple to understand.
Again, if you claim to love God, yet hate a brother, you are a liar.

Liars will not inherit the Kingdom.

How can one love God, who he has not seen, and yet hate his brother, who he has seen?

We have the commandment - love OneAnother.
We have the power to do so...if truly saved...because the love of the Lord is in us.

If you love God, then love OneAnother.
