If you are looking for a pat answer, I have bad news: faith is a lifelong journey, not a destination.
Don't check your brains at the door. As well as free will, you have intelligence. You'll need to be sure that whatever you decide to adopt as a world-view does not betray all the other aspects of your person. So if an idea seems stupid or flaky or inconsistent, dump it! If it were really true then it wouldn't be inconsistent with your experience and the things you know to be true. In fact, use the same method you use to validate other facets of your life. And whatever you choose, keep testing and questioning and refining. Faith is living.
Life is subjective. Don't pretend that you can come up with an objective answer. Can you objectively find love or happiness? Of course not. So, use everything you have seen, felt, and sensed in your faith journey. If you felt serene at some point in your life, was there a hidden message there? Have you ever felt your prayers were answered? Then that is a clue. Listen to your heart.
If the meaning of life were evident or easily found, we'd all have it spelled out to us. But it is indeed mysterious and you need to work at it. After forty years, I have many answers, but even more unanswered questions. Read about others' solutions, find out about existing religions and philosophies, think, meditate and pray. If you ignore the question, you won't get very far!
May you be blessed in your quest.
