So what is God’s plan?

Some Christians believe that our salvation is a bus ticket to heaven, and what we do while we wait for the bus makes little difference. 

Is it Godly management of talents, time and treasure?

It's about our actions and accountability until He comes back or we appear in His habitation.

It comes from the fact that it takes just as much work for the five-talent servant to produce five more talents as it does for the two-talent servant to produce two more talents. This is why the reward given by the Lord, our God is the same. The Master measures success by degrees of effort, as should we.

So what is God’s plan?

Theologian J. I. Packer, in talking about the overarching narrative of the Bible, said, “Its main theme is not human salvation, but the work of God vindicating His purposes and Glorifying Himself in a sinful and disordered cosmos. He does this by establishing His kingdom and Exalting His Son, by creating a people to worship and serve Him, and ultimately by dismantling and reassembling this order of things, thereby rooting sin out of His world.”

So it's about God, to develop them to come closure, to dismantle our way of looking reality and eliminate Sin from the World.
