Interesting questions !
I think the best way we can engage in meaningful and purposeful worship is to live our lives for Christ. Those around us will see what we are all about by our actions. As people see that we are trustworthy, treat people with respect and have a positive attitude, they will want to learn more about us and be around us. They will soon learn what drives us, living for Christ !
There are a lot of people out there that are looking for the answer to a long happy life. They have a lot of material "stuff". They have a family and friends, what seems like the perfect life. They just can not figure out what is missing. Well, it is obvious to me and probably you too. They are missing the faith and grace of God. People are curious when they run across someone who has a positive outlook and is happy. They want to know what the secret is ! This is where we have the opportunity to praise God and thank him for the grace and glory that He has blessed us with.
Just like the groups here on Olivia, we tend to group together by interests. As more and more people get interested in learning about our positive dispositions, they will soon take on their own. As they come in to their own, they add more and more to the worship and bring in those who are following them. This is how we reach people and fellowship with them.
Soooo, to make looooong story short !!! Just be your charming self, live for Christ, give Him the glory . . . . and before you know it, you will have many friends in Christ !!
