Not sure exactly what you mean by not wanting a different spiritual path, just a different outlet? Unless you are asking about other Christian denominations? There is a huge amount of difference in them as far as practices and emphasis. And some of that changes from one congregation to another.
I've been gping to my church for 16 or 17 years, and there has never been a fire and brimstone sermon, but there have been many, many on love.
If you are looking for a new denomination, then try visiting services at a number of different ones to see which congregation "fits" you best. Many churches have a website, and it is common for them to have some sort of statement of faith or summation of their beliefs listed. Look for those that most closely match your beliefs, that speak to what your heart is calling for. Look for churches that have large outreach programs that provide services to others. Even if you do not choose to change your church, you might get ideas of changes you can make within it.
One person CAN change the world, but it does not happen all at once. Once upon a time Mother Teresa was a young nun with no particular impact beyond her own, small interactions. Any yet by the time she died, she had made a HUGE impact in bettering the lives of millions. Once upon a time Bill Gates was a typical kid. He started building computers out of his garage. Look at how he has revolutionized technology and changed the world; and now he is pouring many millions of dollars into humanitarian and charitable causes. Billy Graham was a poor young kid, but he grew to create a ministry that is known world-wide, and most of his sermons dealt with love. So do not discount what you can do personally, or the amount that you can influence those around you.
I do not know how much of the Bible you read, but I would suggest that you read the New Testament from start to finish, and when scripture from the Old Testament is given, follow that path and read there as well. You might want to read the Gospels side by side as they each tell the story a bit differently, from different perspectives. John is significantly different than Matthe, Mark and Luke. You should also read the Old Testament through, but it has a great deal more violence, and in some books, finding love is HARD. In others it is SO apparent.
A lot of people dislike the term religious; I am not one, to me it is very much being spiritual. I believe that if you live a spirit-filled life, you are religious. The intent of religion is to worship God. We all worship in our own ways, but doing what is pleasing to him is the first thing he calls for. He leads people in many different directions; we have different talents and gifts. It sounds like he is calling you to a purpose. You personally cannot do EVERYTHING, but you can do everything that he is asking. Maybe you are called to lead and organize people to fill the needs of many. Or maybe you are called to personally fill needs.
