Faith

The subject on my mind today is faith I know this is a very personal subject but I would love input from any who care to add, I have such a strong faith in God ,in his son Jesus Christ and the purpose of this life and where we will go when we die. I know God loves us so much and provided the atonement through His son Jesus Christ so we can return to live w/ Him again I know all these things and they are such a comfort to me . But I have always struggled w/ how to know what is enough on my part and what part I can turn over to the Lord. Does anybody else struggle w/ this or am I just lacking in the Faith it takes to know……?????
