“One of the greatest misconceptions of heaven is that it is static, unchanging, and immutable, as if to say that all we get we get all at once, at the beginning. The idea many have is that we are transformed at its inception as much as we ever will be. No. But to think that the happiness of heaven is unchanging minimizes its glory…

The basis for knowing this to be true is the biblical reality of God’s inexhaustible plenitude.

We must never forget that even in heaven only God is immutable or unchanging. WE are ever subject to greater transformation and improvement. But it is always a change from one stage of glory and knowledge and holiness to the next higher stage of glory and knowledge and holiness. It is one thing to be free of imperfection, but another to experience perfection perfectly. We will be perfect in heaven from the first moment we arrive in that we will be free from defect, free from sin, free from moral corruption and selfishness. But that perfection is finite, because we are finite. It is alway subject to expansion. There is change, but always for the better!

Heaven is not simply the eradication of earthly sin and imperfection. To say that in heaven I will no longer hate God is not the same as loving him perfectly. My love can be free from corruption and selfishness without being as perfect and intense as is possible. To say that my love for God is absolutely perfect and cannot be improved upon implies that I know everything that can be known of him and that I know it in exhaustive detail.”
