The Bible does not speak about feelings and passions. The Bible speaks about commitment and everlasting bounds, something not familiar to this new generation.
Why am I here on this earth? There is no right or wrong answer to that. We are all different and we must discover the true nature of that question in our lives.
This is how I see it. God had mercy on me and showed me His grace by saving me. He was the one saving me, He is my savior and if He is my savior, there is nothing to worry about. Nothing and nobody can snatch me from His hands.
