The God kind of Love produces the God kind of Faith which pleases God. To love one another is a commandment.
A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another. John 13:34-35 KJV
There is no escaping it. God expects it of those who are His.
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us. 1 John 3:23-24 KJV
