It's a general "Be Excellent to One Another" a'la Bill and Ted mindset, but if I had to boil it down to core concepts... Hmm.
Matthew 22:40
Hearing that Jesus had silenced the Sadducees, the Pharisees got together. One of them, an expert in the law, tested him with this question: “Teacher, which is the greatest commandment in the Law?” Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind. This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself. All the Law and the Prophets hang on these two commandments.”
When confronted with religious dogma, Jesus came up with a very similar answer. The Bill and Ted mindset in this case is completely the way to go. However, you're missing the whole "Love the Lord
your God" part in your stance. I'm not saying this to say "Oh you're going to hell!", because only God can judge that. There's so much joy in the fact that God is good; he not only loves us but he IS love; he created us in his image; died for us; wants us to live life to the fullest; gives us wisdom freely; breaks strongholds of sin in our lives; etc, etc etc. You actually do strive to do good to others. Not saying that you're perfect or anything, but neither are me or Zane or anyone else for that matter. But, "No one is good but God alone". By acknowledging God's existence and his authority as Lord (He is Lord whether you choose to acknowledge it or not), you can live a spirit-filled life that has meaning, purpose, power, joy, etc. He is the giver of true-knowledge, life, joy, etc. God really is so good! God's creation cries out how good he is.
Psalm 19:1-6
The heavens declare the glory of God;
the skies proclaim the work of his hands.
Day after day they pour forth speech;
night after night they reveal knowledge.
They have no speech, they use no words;
no sound is heard from them.
Yet their voice goes out into all the earth,
their words to the ends of the world.
In the heavens God has pitched a tent for the sun.
It is like a bridegroom coming out of his chamber,
like a champion rejoicing to run his course.
It rises at one end of the heavens
and makes its circuit to the other;
nothing is deprived of its warmth.
