Love is one of the most elastic words in the English language. We love our mother, we love pizza, we love our dog, we love our team, we love ice cream, we love "it" whatever "it" is, or whoever it is. We will choose to love someone or something in some way, isn't that true?
We choose to believe in love. We place our faith in love. We are faithful to the object of our love because we have faith in it. Otherwise, we would not truly love it.
Belief and faith are related in some way or ways. I am not an expert enough to define it. However, most of us could give a number of examples of that connection between belief and faith and connect it to love.
"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have eternal life." (John 3:16 ESV) So, God Himself connects the idea of believing and of loving in the same sentence.
To be sure, God's form of love is what is called agape love. It is a love that gives without counting cost or calculating return. However, God does discern whether He is loved in return by whether or not we keep His commandments. "If you love Me, keep My commandments." (John 14:15 ESV)
For us to know that God loves us more than we can ever deserve, that He calls upon us to believe in His only begotten Son, calls for a response from us, does it not? Absolutely! However, to understand that we respond in love towards Him by keeping His commandments would give us pause, unless....Unless we understood that those commandments preserve us, enable us, and encourage us as a result of God's compassion. But, that's another theme for another time.
Back to the idea of believing in love, we can choose to love God. We choose to honor, that is to assign value to, God's love for us. If and when we do so, we will find a joy in our spirit that could never be experienced by any way other that finding and responding to the love of God in Jesus Christ.
However, we can also choose to dishonor God's love for us. That means more than setting no value on it. By dishonor, we are saying that we assign negative value to God's love for us. It becomes a nuisance to us. It cramps our style. We wish to be the captain of our own souls, the master of our own fate, etc. So, God's love, because it is attached to the notion of His commandments, becomes poison to our self purposes.
In this case we find people choosing to honor self importance. They may first deny the truth, the importance, or even the existence of the love of God in Jesus Christ. Or, they may choose to deceive themselves into believing that God honors their affections as they choose to define them. This is even if the Bible, the Word of God, describes such affections as "vile."
Those of us who choose to ignore God's commandments wind up creating our own. We find ourselves choosing to value ideas and feelings that encourage self importance over importance of God's love in Christ.
We choose to substitute another thing for which we choose to find value. On that person, experience or thing, then, we will invest ourselves. We will set our affections. We will choose to believe in the love of that "other".
We will all believe in love of something and someone. We all will make those choices. So, what will you choose? I choose John 3:16.
