Only God

Only God decides the definition of love. 
Not the US Government. 
Not the United Nations.
Not any Parent-Teachers-Organization.
Certainly no university staff organization.
Not even parents and grandparents get to decide that. It’s in the New Testament. 

If you don’t have a Bible, it’s on the internet. A good place to start is in the New Testament, with The Gospel of John.
Those that can’t read can get Bible audio on the internet. is a good place. 

You might say, “I don’t care if people love me as long as they respect me.” 
But I say, we must be able to love humanity before we can truly respect anyone, before we can show them any dignity or concern. You can’t be respected by people who are unable to truly love humanity. 
For example, I find it amazing that anyone would hope to receive true love from anyone that is pro-abortion, for those people kill their own flesh and blood for the sake of personal convenience. 

Before you can find love, you have to know what love is, then look for the people that live it. 
Next , only God defines perfection and sin; mercy and justice. 
If we were perfect, we could deserve to go to heaven. Heaven is a sinless place, and evil people are not allowed in. 

But we are all flawed; therefore we will each receive either mercy or justice on our particular Judgement Day. 
There are two Judgement Days; a Review and Reward Day for those who submit to the Holy Trinity, 
There is also, a punishment hearing for those that have outright refused Him, and for those who pretend to be Christians, but just use religion for their own benefit. 
Their eternal punishment will be set then, and again, God, not us, sets the punishment.

We will each be at one of the two judgment Days. Those who have chosen to submit and/or love God will receive mercy from their sins. 
Those who reject God will be sent away into Hell for their sins, some of which they didn’t know they committed, because they refused to learn about God. 
Internet search: Mathew 25: 31-46.

So if every human but Jesus has sinned, and Heaven has no evil in it, how do we get there? 
If we become born-again, we are given many promises by God. 
One of the most important promises God gives us is often the most overlooked; the Promise of Transformation. 

The Promise of Transformation: 
1 John 3 3:  "See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. 2 Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears,[a] we shall be like him, for we shall see him as he is. 3 All who have this hope in him purify themselves, just as he is pure." (NIV) 

“…when Christ appears, we shall be like him, for we shall see him as he is.” 

The Transformation will be instantaneous. 
His crucifixion brought payment for our sins. His appearance will transform us and make us suitable for Heaven. 
Nothing else is needed, we just need to aim toward purification until we see Him.
