Life and Purpose in Time? What is the purpose of life constrained by Time and physics?

The most relevant and all-consuming question in the life of a man or woman is: “Do you believe that Jesus Christ is God who died to pay your sin-debt, a debt to God the Father that you could not pay yourself?” How one responds to this question will determine whether or not their life within the Ream of Time is lived and ultimately culminates with purpose and glory or nihilism and futility. With all of our cares and concerns in this life, the only subject truly worthy of ultimate consideration is the primary reasoning for our existence in Time; that is, our relationship with the One who created us and created this Universe for cause with rapidity i.e. Jesus Christ our God.
